Re^4: Parse string and extract word after specific pattern

Apparently, the first argument to split is always treated as a regex, because split '\.', $s worked.

The documentation implies a string and a regex are treated differently:

(such as ' ' or "\x20" , but not e.g. / / )

Seems that, as luck would have it, I never happened to use a regex meta character split 'x'.

In light of the described differences in handling of ' ' vs / /, the documentation should state that the first argument is always treated as a regex even supplied as a string.

It does at the very beginning of split:

    split /PATTERN/,EXPR,LIMIT
    split /PATTERN/,EXPR
    split /PATTERN/
    split

There are only three exceptions, space, empty regex, and /^/ .
