No difference between new simple type and type alias

[uschuster]

There is no difference in the AST between a new simple type and a type alias, but there should be one. Both AST entries consist of a node of type ntTypeDecl and a child node of type ntType.

Sample

type
  TNewInteger = type Integer;
  TIntegerAlias = Integer;

Current AST of type section

ntTypeSection
|- ntTypeDecl  [anName = TNewInteger]
   |- ntType   [anName = Integer]
|- ntTypeDecl  [anName = TIntegerAlias]
   |- ntType   [anName = Integer]

[RomanYankovsky]

|- ntTypeDecl  [anName = TNewInteger, anKind = Alias]
   |- ntType   [anName = Integer]

This would be alright?
