Wouldn't some of the lists (like a set of checkboxes with the same name) that take a variable number of arguments wind up sometimes being an array and other times being a scalar? That would suck.

    Actually, CGI's import_names() method imports every parameter as a scalar and as an array. The scalar will hold the first value for the parameter; the array will hold all the values, of course.

    The array be safely used in all cases, but the scalar is available for when you know that a parameter should only have a single value.

      *grin* Hmmm, ok how about this, read the post as though I actually replied to the main thread rather than another post. (doh) My point was the original post was evil when in came to variable number same-name form posting. He tests on the item count, so sometimes you get $Blah::boxes and other times you get @Blah::boxes but NOT both like CGI. =)
