Re: Re: perl -x to test while developing (riddles)

-mstrict does nothing useful, just like 'require strict;'.
Thanks, fixed.
Although I maybe it's more like 'use strict ();'

$ perl -mstrict=vars -le 'print $x**$y;'
Global symbol "$x" requires explicit package...

perlrun says "Any meaningful switches on that line will be applied" but "meaningful" seems to be strangely implemented. At least with 5.6.1.

Here's another one:

$ perl -x
#!perl -wl -Mstrict -MB -MCGI
Argument "MCGI" isn't numeric in subtraction (-).
Argument "-MB" isn't numeric in subtraction (-).

Although I maybe it's more like 'use strict ();' That's indeed what `-m` means, which, to be entirely precise, is like `BEGIN { require strict }`. Makeshifts last the longest.	[reply]
