Re^2: (nearly) readonly globals

Using local creates a temporary instance of the named variable, and you can do what you like with it.

But this does not apply to all special globals, i.e.:

% perl -e 'local $1 = 1'
Modification of a read-only value attempted at -e line 1.

% perl -e 'local $^S = 1'
Modification of a read-only value attempted at -e line 1.

Yes - see local, resp. the documentation referenced by it, Private Variables via my() in perlsub.	[reply]

I don't give up: `% bleadperl -Mstrict -wE 'for $1 ( 10..13 ) { say $1 }' 10 11 12 13` [download] And now, these globals loose their magic: `% bleadperl -Mstrict -wE 'for $1 ( 10..13 ) { $1 =~ /^(\d)/; say $1 }' 10 11 12 13` [download] -- Frank	[reply] [d/l] [select]
