    Allocate variable on JVM stack as an optimization. This means load is implemented as a dup instruction. (This is no faster on decent JVMs, but the bytecode is more compact.)

    True for a variable inside a pattern, but not the top of the pattern. E.g. for a pattern [a [b c]] there is a main declaration for the incoming value - which does not have PATTERN_NESTED set. There are three declarations a, b, and c - which do have PATTERN_NESTED set. In addition there may be helper variables which are anonymous (i.e. getSymbol() returns null), like the match for the sequence [b c]; these also have PATTERN_NESTED set.

    List of ApplyExp where this declaration is the function called. The applications are chained using their nextCall fields. This is list is built twice: First in PushApply (for use during InlineCalls), then the list is clearest, then rebuilt in FindTailCalls. This is because InlineCalls may inline and re-arrange the call graph. The chain is not built the second time if STATIC_SPECIFIED.

    Parameters:
    cname - name of class containing field
    fname - name of static field
  - getDeclarationValueFromStatic
```
public static Declaration getDeclarationValueFromStatic(java.lang.String className,

```
  - getInitValue
```
public Expression getInitValue()
```
    Get the "initial value" expression. This is used for the initializing value in a LetExp, a parameter's default value, or for pattern-matching.
  - setInitValue
```
public void setInitValue(Expression init)
```
  - hasUnknownValue
```
public boolean hasUnknownValue()
```
  - getValue
```
public final Expression getValue()
```
    The value of this Declaration, if known. Usually the expression used to initialize the Declaration, or null if the Declaration can be assigned a different value after initialization. Note that this is the semantic value: If the INDIRECT_LOCATION is set, then getValue is the value after de-referencing the resulting Location. An exception is if isAlias(); in that case getValue() is an expression yielding a Location which needs to be de-referenced to get this Declaration's actual value.
  - getValueRaw
```
public Expression getValueRaw()
```
  - setValue
```
public final void setValue(Expression value)
```
    Set the value associated with this Declaration. Most code should use noteValue instead.
  - getConstantValue
```
public final java.lang.Object getConstantValue()
```
    If getValue() is a constant, return the constant value, otherwise null.
  - hasConstantValue
```
public final boolean hasConstantValue()
```
  - getLambdaValue
```
public LambdaExp getLambdaValue()
```
  - noteValue
```
public void noteValue(Expression value)
```
  - noteValueConstant
```
public void noteValueConstant(java.lang.Object value)
```
  - noteValueUnknown
```
public void noteValueUnknown()
```
  - noteValueFromSet
```
public void noteValueFromSet(SetExp setter)
```
  - noteValueFromLet
```
public void noteValueFromLet(ScopeExp letter)
```
  - noteValueFromApply
```
public void noteValueFromApply(ApplyExp app,
                      int index)
```
  - patchSymbolFromSet
```
public boolean patchSymbolFromSet()
```
    Set symbol from initializing SetExp. Used for an export-only alias, for handling export-with-rename.
