Re^3: strptime("%Y-%m") in perl6

Nor sure to really understand your requirement, but what about this:

> for <1 5 3 13> -> $month { say Date.new(2019, $month, 1 )}
2019-01-01
2019-05-01
2019-03-01
Month out of range. Is: 13, should be in 1..12
  in block <unit> at <unknown file> line 1

I need to check command line args. I expected perl6 to be simple as: `"parse ARGS[0] as %Y-%m od die"` [download] Just one sentence without additional ARGS[0] manipulation.	[reply] [d/l]

In Perl6, the special MAIN subroutine, if any, receives the arguments passed to the program and can be used to check their type and validity: `~ perl6 -e 'sub MAIN (Int $month where 1 <= $month <= 12) {say "Succes +s";}' 4 Success ~ perl6 -e 'sub MAIN (Int $month where 1 <= $month <= 12) {say "Succes +s";}' 14 Usage: -e '...' <month> ~ perl6 -e 'sub MAIN (Int $month where 1 <= $month <= 12) {say "Succes +s";}' 8.5 Usage: -e '...' <month>` [download] Is this the type of thing you're after?
