[lazarus] FPC Request

[Shane Miller]

Defining a TYPE as

TSomeType = Type Word; 

creates a type that is not associated with a Word.  For example, if you define some types as 

type
T1 = Word;
T2 = Word;

TSomeType = type Word;

then T1 and T2 are identical to words, but TSomeType is actually a NEW type.  Delphi uses this to override the normal property editor in their IDE.  If they defined a published property as a T1 and selected it in the object inspector, they would edit it like they would edit a WORD value.

If they defined a published property as a TSomeType and tried to edit it in the object inspector, you could create your own property editor for that type.  It's NOT associated with a word and therefore can be edited differently.

I think for now, you simply need to allow the declaration, and we can work on the other parts of that later.

If someone can explain what it needs to do, including an example to test
it.
