Re^2: While loop does not terminate

> that I moved the get_value() function to another package where it did not have access to a variable it needed to work properly.

how is this possible to happen silently under strict???

 DB<232> use strict;use warnings; print $XXX
lobal symbol "$XXX" requires explicit package name 
(did you forget to declare "my $XXX"?) at (eval 263)
[c:/Perl_524/lib/perl5db.pl:737] line 2.

Strictures don't bleed through to included packages. Consider: `# noname.pl: use warnings; use strict; use lib '.'; use noname1; print noname1::get_value(); # noname1.pm: package noname1; sub get_value { return $missingVar // 'Bogus value'; } 1;` [download] Prints: `Bogus value` [download] Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond	[reply] [d/l] [select]

I supposed it's obvious that strictures must be used in each file, since pragmas are scoped. `# noname1.pm: use strict; use warnings; package noname1; sub get_value { return $missingVar // 'Bogus value'; } 1;` [download] now running ... `# noname.pl: use warnings; use strict; use lib '.'; use noname1; print noname1::get_value();` [download] output `Compilation started at Sun Dec 13 22:16:46 C:/Perl_524/bin\perl.exe -w d:/tmp/pm/noname_strictures/noname.pl Global symbol "$missingVar" requires explicit package name (did you fo +rget to declare "my $missingVar"?) at noname1.pm line 9.
