[fpc-pascal] Generic constants with generic type

[Andrey Zubarev via fpc-pascal]

Hi all!
With the existing syntax of constants, it is good to pass array boundaries,
but bad to initial parameter values. What do you think about such
constructs:

GTValue<GValueType; const GMin,GDefault,GMax:GValueType>=...

It is currently simply not possible to reference earlier type parameters
inside the parameter clause. This affects code like this as well: generic
TSomeGeneric<T; S: ISomeOtherGeneric<T>>
Once that is fixed your case will probably work as well as long as the type
is one for which untyped constants can be declared.

Ok. Thanks!
For this already there is a bug report? to notice when it will work?

Best keep an eye on this one and then test again once it's solved:
