in reply to Basic help with mapping

map works... but there is a feeling that it is not needed. If I do it, I will simply:

use strict; use warnings; use Data::Dumper; my $AoH_orig = [ { 'title' => 'aaa-aaa', 'name' => 'tom' }, { 'title' => 'bbb-bbb', 'name' => 'kathy' }, { 'title' => 'ccc-ccc', 'name' => 'bill' } ]; for (@$AoH_orig) {$_->{'title'} =~ s/-/_/g}; print Dumper($AoH_orig);

Which gives you what you wanted:

$VAR1 = [ { 'name' => 'tom', 'title' => 'aaa_aaa' }, { 'name' => 'kathy', 'title' => 'bbb_bbb' }, { 'name' => 'bill', 'title' => 'ccc_ccc' } ];

[1nickt]: folks, would you say that 1.0 is an integer ?
[Lady_Aleena]: 1nickt, I wouldn't, but I'm not normal.
LanX aggrees, LA isn't normal ;-P
[Lady_Aleena]: LanX, thanks bunches.
[Lady_Aleena]: Rigth now I'm ranting in my head about an old subject.
[1nickt]: Hm, that is, how to prevent Perl from turning 1.0 into 1? I feel sure this must be an faq, but am reading perlnum and not finding the answer ...
[Lady_Aleena]: 1nickt, why does it matter in this case?
[1nickt]: Hm, perhaps this? "Operators which expect an integer force the argument into the integer format."
[1nickt]: Can this be? So print
[1nickt]: ... "expects an integer" ?
