copy last n values of stack

[goyalyashpal]

• this may help in some cases where the fork fails

• also, this may provide a better alternate to the over over phrase which copies last 2 values on stack

Parametric stack copying is not something I'd like to encourage. If you want to copy stack values, you should know exactly how many there are at the time you write your program. I think ,, is a fine idiom. Fork more than 2, fork is adequate.

yeah, makes sense. so, how about it allow only literal value? similar to how if used to take only 0|1 literal in v0.0.17

I think ,, is a fine idiom.

yep, no prob with it; the issue is that there's no way to do for more than 2

Fork more than 2, fork is adequate.

umh, sorry?

But with if, you can pass it a value that is the result of a another computation. No Uiua functions currently require that their arguments are known at compile time.

For more than 2.
