No doubt, but this will lead to a bloated binary. I want less code (both

Well, it would be one instantiation per unique type it was used on.
I know. See below.
So if you had five hand-written helper functions for different types, and
replaced all of them with the use of a single generic function, you'd still
end up with just five functions worth of assembler code (i.e. the same
amount you had to begin with.)
Yes, I know. But the goal is to have 'is/as'. Then there is at best only 1
helper
function for all enumerateds.
I have a Delphi project that uses really lots of generics. The decrease in
compilation speed and increase in binary size is truly noticeable.

In general, I strive to minimalize the use of generics or avoid them at all.
IMO there are little use cases that really justify the use of generics.
But that's a highly personal opinion.
