Description:

BRVariableNode is an AST node that represent a variable (global, inst var, temp, etc.).

Instance Variables:
	token	<BRValueToken>	the token that contains our name and position

Class protocol:

 identifierToken: anIdentifierToken

 named: aString

Instance protocol:

 addReferencedVariablesTo: aCollection

 definingSequence

Return the sequenceNode (i.e. the scope) that defines this variable
or nil, if no sequenceNode does

 lineNumber

(comment from inherited method)
lineNumber isNil ifTrue:[

 name

 precedence

 startWithoutParentheses

 stopWithoutParentheses

 token

 tokenPosition

 = anObject

 equalTo: anObject withMapping: aDictionary

return true, if I am equal to another node, with a given variable name mapping.
Side effect: update the mapping dictionary as required to reflect a matching mapping (if possible)

 equalTo: anObject withSelectorMapping: aDictionary

return true, if I am equal to another node, with a given selector name mapping.
Side effect: update the mapping dictionary as required to reflect a matching mapping (if possible)

 hash

 variableNodesDo: aBlock

evaluate a Block for all variable nodes.

 identifierToken: anIdentifierToken

 highlightInCodeView: aCodeView

 leftClickMenuInCodeView: aCodeView

 rightClickMenuInCodeView: aCodeView

 copyInContext: aDictionary

 isReferringToAnExceptionInContext: aSearchDictionary

true iff:
(node is a global variable or node is a class variable)
and the variable refers to an Exception class (but not a Notification)

 isClassVariableInContext: aSearchDictionary

not true - also returns true for class vars and globals

 isGlobal

Return true if the variable node is for
a global variable, false otherwise.
Actually wrong: also returns true for inst- and class variables
(i.e. anything that is not a block- or method local)

 isImmediate

 isInstanceVariable

not true - also returns true for class vars and globals

 isLocal

Return true if the variable node is for
a local variable, false otherwise.
Returns true for anything that is a block- or method local

 isRead

Return true, if the variable is read

 isSelf

true if I am the self-variable node

 isSuper

 isTemporary

Return true if the variable node is for
a temporary variable, false otherwise

 isVariable

 isVariableNotInLeftHandSideOfAssignment

Returns true iff receiver is variable node but not
in left-hand side of assignment

 isWrite

Same as isWritten - bad naming here

 isWritten

Return true, if the variable is written

 reads: variableName

 references: aVariableName

 acceptVisitor: aProgramNodeVisitor
