Hi,
Also assume you have a record and a hashmap that stores them. Now you
add a string to the record which turns it into a managed one and
suddenly your code will no longer work, probably resulting in subtle
bugs or memory leaks. That's /not/ what should happen for merely
adding a string.

I think constants in generics may be the only way to create dynamically sized
types at compile time (via static arrays). That seems like a really narrow
usage but it opens a lot of doors most of us have probably never thought about.
I suspect in time more good usages will be discovered.

If so, can I finally have my Extended Pascal schemata?

Hi,
perhaps it could be used to merge specializations (if fpc cannot do
that on its own):
Like when you have a hashmap THashMap, and need three

It is basically three times the same hashmap,

I think you're right. Here's what I'll say next time: They're for composing
types of dynamic size at compile time. :)

It can be quite useful. You can do something similar (I hope):

Thank you Ryan and Sven. Your work is much appreciated as usual.
However, Michael beat me to it in asking how this feature is useful. I am
sure there might be use cases, but for right now I am coming up without any
real advantages. Could anyone with better insight than me please explain?

Excellent! Thanks for getting this merged. It was a long battle but it's
