in Perl, everything is a string until used in a numeric context

I don't think that is true.

In your example you put quotation-marks around the value, so little surprise that you end up with a string...

Consider this:

use Devel::Peek; my $a = "1"; my $b = 2; print Dump($a); print Dump($b);
This produces:

SV = PV(0x98c9700) at 0x98ea3f8 REFCNT = 1 FLAGS = (PADMY,POK,pPOK) PV = 0x98e6368 "1"\0 CUR = 1 LEN = 4 SV = IV(0x98ea474) at 0x98ea478 REFCNT = 1 FLAGS = (PADMY,IOK,pIOK) IV = 2
As you can see $a is a string "PV", while $b is an int "IV", even thought it was never used in an numeric context.
