Hello Monks,

I was in the middle of writing a sub/function in my script and I was curious about the following circumstance, and was
wondering if one of the methods below is preferred or recommended over the other. The situation is when you pass ONLY
a single argument to a sub-routine. So there will only ever be one argument passed to my sub/function...

Is one of these methods preferred/recommended over the other:

METHOD #1 
sub myFunction
{
     my $arg = shift;
     #blah blah blah, do some stuff.....
}
myFunction($myArg);

METHOD #2 
sub myFunction
{
     my $arg = @_;
     #blah blah blah, do some stuff.....
}
myFunction($myArg);

[download]

METHOD #3 
sub myFunction
{
     my $arg = $_[0];
     #blah blah blah, do some stuff.....
}
myFunction($myArg);

I'm not sure if there are other ways to grab the argument besides those, but are any of those the preferred/recommended
method over the other?


Thanks in Advance,
Matt
