I represent an abstract semantic error thrown by the SemanticAnalyzer.
Semantic errors can be unknown variable errors, etc.
See my subclasses for concrete errors.

The IDE should catch instances of Semantic error to deal with them when compiling!

I get signaled when a pseudo variable gets assigned.!

variableName

variableName: aString
	variableName := aString

!ShadowingVariableError commentStamp!
I get signaled when a variable in a block or method scope shadows a variable of the same name in an outer scope.!

I get signaled when a variable is not defined.
The default behavior is to allow it, as this is how Amber currently is able to seamlessly send messages to JavaScript objects.!
