my ($filename) = "/path/to/file";
my ($filemode) = "immolate";
my ($opmode) = "seek";
my ($filetype) = "image/gif";
As a matter of style (and occasionally necessity), I leave off the parens on
those leftsides if the right side needs to be evaluated in a scalar context.
Otherwise, I might wonder which one you meant of:
my ($filemode) = ("immolate"); # list context
my $filemode = "immolate"; # scalar context
And yes, it really does matter when you get into subroutine arg grabbing, like
my $count = @_; # get the length
or should that have been
my ($count) = @_; # get the first arg
So, make your left side and your right side agree, and I don't have to scratch
my head wondering where you are headed.
