Now that would be a duplicate identifier error but that may be changed for
Delphi compatibility? That indeed would break any possible shorthands. Maybe at
least the specialize could be omitted because of the grammar which is so
annoying. :)
To the extent I have a todo list I’ve had plans to make a mode switch for
“generic keywords” so you could disable them in Object Pascal mode (Svens
idea). That would fix the specialize problem but honestly I kind of like the
generic keyword as it’s a prefix and makes the type more clear. It’s the
specialize keyword I have a problem with.
