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
