Hello all,
If I make a typo and write a single "equals" operator here:
#!/usr/bin/perl
use strict;
use warnings;
my $foo = 1;
my $bar = 2;
if ($foo = 2) {
print "yes\n";
}
else {
print "no\n";
}
...then the "warnings" pragma works OK and tells me "Found = in
conditional, should be ==..."
But if I make the same typo and write a single "equals" operator there:
#!/usr/bin/perl
use strict;
use warnings;
my $foo = 1;
my $bar = 2;
if ($foo = $bar) {
print "yes\n";
}
else {
print "no\n";
}
... then I get no warning; the script output is "yes".
Why is it so?
How could I catch such typos?
