description: Expressions
RCS: $Id$
This file contains the module `Expression\', which contains data types for
describing expressions, after they have been examined by the
static analyzer in the module `StaticExp\'. There are of course
great similarities with the expression types in the `Absyn\'
module, but there are also several important differences.
No overloading of operators occur, and subscripts have been
checked to see if they are slices. All expressions are also type
consistent, and all implicit type conversions in the AST are made
explicit here."
