in reply to one liner automagic strftime()

In the substitution operator the right hand side is evaluated in scalar context and thus localtime returns the formatted date as a string as per documentation:

use strict; use warnings; my @x = localtime 1503403724; print "@x\n"; my $x = localtime 1503403724; print "$x\n"; my $z = "ccc"; $z =~ s/ccc/wantarray()?"list":"scalar"/e; print "$z\n";

    Arf. So no magic, just the list / scalar context. I have always missed that paragraph of the localtime() perldoc... Thanks.

      Perl surely falls into that category...
