There is nothing unclear about if (@ARGV == 0) which quite intuitively translates to "if the number of arguments is zero." Your alternatives are all fine, too, but there is no reason other than personal preference to prefer one over the other.

There is nothing unclear (or evil, odd ) about your statement :) My small critic was not about clarity, but style -- perlishness

"if no arguments" is more natural, its perlish

If you feel like putting a number on it, you might say "if zero arguments" , but it doesn't follow the code

if( @ARGV == 0 )
if numarg is zero
if( 0 == @ARGV )
if zero is numargv
