768 The C<warnings> pragma gives control over which warnings are enabled in

773 This pragma works just like the C<strict> pragma.
a16537d2fe07 <xfix> tar xf perl-5.22.2.tar.gz # Ah, whatever, I\'m doing it anyway
HackBot
parents:

774 This means that the scope of the warning pragma is limited to the

HackBot

810 Before the introduction of lexical warnings, Perl had two classes of
a16537d2fe07 <xfix> tar xf perl-5.22.2.tar.gz # Ah, whatever, I\'m doing it anyway
HackBot
parents:
diff changeset
811 warnings: mandatory and optional.

813 As its name suggests, if your code tripped a mandatory warning, you
a16537d2fe07 <xfix> tar xf perl-5.22.2.tar.gz # Ah, whatever, I\'m doing it anyway
HackBot
parents:
diff changeset
814 would get a warning whether you wanted it or not.
a16537d2fe07 <xfix> tar xf perl-5.22.2.tar.gz # Ah, whatever, I\'m doing it anyway
HackBot
parents:
diff changeset
815 For example, the code below would always produce an C<"isn't numeric">

824 example, in the code below, an C<"isn't numeric"> warning will only
