Here is the code:

$seen{$curr} = 1;

my question is: what will @allwords now contain, or how would the entries in the @allwords array be different after this manipulation?
Thank... (3 Replies)

Perl::Critic::Policy::CodeLayout::ProhibitHardTabs(3) User Contributed Perl Documentation Perl::Critic::Policy::CodeLayout::ProhibitHardTabs(3)NAME
Perl::Critic::Policy::CodeLayout::ProhibitHardTabs - Use spaces instead of tabs.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Putting hard tabs in your source code (or POD) is one of the worst things you can do to your co-workers and colleagues, especially if those
tabs are anywhere other than a leading position. Because various applications and devices represent tabs differently, they can cause you
code to look vastly different to other people. Any decent editor can be configured to expand tabs into spaces. Perl::Tidy also does this
for you.
This Policy catches all tabs in your source code, including POD, quotes, and HEREDOCs. The contents of the "__DATA__" section are not
examined.
CONFIGURATION
Hard tabs in a string are always forbidden (use " " instead). But hard tabs in a leading position are allowed when they are used to
indent code statements, "qw()" word lists, and regular expressions with the "/x" modifier. However, if you want to forbid all tabs
everywhere, then add this to your .perlcriticrc file:
[CodeLayout::ProhibitHardTabs]
allow_leading_tabs = 0
NOTES
Beware that Perl::Critic may report the location of the string that contains the tab, not the actual location of the tab, so you may need
to do some hunting. I'll try and fix this in the future.
