@cdome Thank you.
I am writing function like map, it will take the type array, slice, seq,
iterator, etc as parameter, because the iterator cannot be treated as typed, so
I cannot use typed(If the paramter type is typed, the function in the code can
compile successfully).
The code like this works:
type outType = type((
block:
when compiles(seq1.len) and not (seq1 is string):
when seq1 is array[1, Slice]: (var it{.inject.}:
type(seq1[0].a);)
else: (var it{.inject.}: type(seq1[0]);)
elif seq1 is Slice: (var it{.inject.}: type(seq1.a);)
else: (var it{.inject.}: type(seq1);)
op))
var result: seq[outType] = @[]
I have several function like this, so I hope I can use an template to wrapper
the code rather than copy/paste, but if I put the code in another template, I
get the compiler error.
