This is what might happen:
for thing in
iterator res: string {.inline.} =
for r1 in iter1():
yield r1
for r2 in iter2():
yield r2
This is what you actually need:
template chain(iter1, iter2: typed, body: untyped) =
block:
for str {.inject.} in iter1():
body
for str {.inject.} in iter2():
body
iterator thing1: string =
yield "A"
yield "B"
yield "C"
yield "D"
iterator thing2: string =
yield "E"
yield "F"
yield "cookiemonster"
chain(thing1,thing2):
echo(str)
