Why does the first example below not work?
## First example
type ProcSimple = proc(x:int)
proc doSimple(x:int) {.procvar.} =
echo "ran ok"
var b:tuple[a:ProcSimple,b:ProcSimple]
b = (a:doSimple,b:doSimple) ## Error: Mismatch
b.a(0)
The following is my workaround, by wrapping a procvar in a variable which is
then used to create the tuple.
## Second example
type ProcSimple = proc(x:int)
proc doSimple(x:int) {.procvar.} =
echo "ran ok"
var b:tuple[a:ProcSimple,b:ProcSimple]
var procRef:ProcSimple = doSimple ## this seems silly
b = (a:procRef,b:procRef)
b.a(0)
