It's in there:
If LIMIT is specified and positive, it represents the maximum number of
fields the EXPR will be split into, though the actual number of fields
returned depends on the number of times PATTERN matches within EXPR.
If LIMIT is unspecified or zero, trailing null fields are stripped
(which potential users of "pop" would do well to remember). If LIMIT
is negative, it is treated as if an arbitrarily large LIMIT had been
specified. Note that splitting an EXPR that evaluates to the empty
string always returns the empty list, regardless of the LIMIT
specified.
my @F = split ',', $line, -1;
