| Summary : Produces warnings when unused variables are detected
|
Description :
*Note:* The author no longer maintain this module. Consider the Test::Vars
manpage if you detect unused vars as a unit test.
This pragmatic module extends lexical warnings to complain about unused
variables.
It produces warnings when a \'my\' variable or \'state\' variable is unused
aside from its declaration.
Given you write a subroutine like this:
sub f{
my($x, $y, $z) = AATT_;
$y++; # used
return sub{ $z }; # used
}
The code above will be complained about \'$x\', because it is used nowhere
aside from its declaration.
You should write \'f()\' like this:
sub f{
my(undef, $y, $z) = AATT_;
$y++; # used
return sub{ $z }; # used
}
Here, one will see the obvious intention to ignore the first argument of
\'f()\'.
The check routine works only at the compile time, so it affect nothing
about the run time.
