Mac Forum / Programming / Perl / July 2006Mac Perl bug?
Why? $a = "1 2 3"; 1 2 3 split / /, $a; [1, "", 2, 3] split " ", $a; [1, 2, 3] -- Juan Falgueras Profesor del Depto. de Lenguajes y Ciencias de la Computación Universidad de Málaga Ende asked... > Why? > [quoted text clipped - 4 lines] > split " ", $a; > [1, 2, 3] Using a single space as the string on which to split triggers a special case: from "perldoc -f split" specifying a PATTERN of space (' ') will split on white space just as "split" with no arguments does.

While this is mentioned in the docs for split(), it could perhaps be written somewhat better.
