Correction: -foo is NOT a bareword. It is a unary - in front of a
bareword.
>From perlop:
Unary "-" performs arithmetic negation if the operand is
numeric. If the operand is an identifier, a string
consisting of a minus sign concatenated with the identifier
is returned. Otherwise, if the string starts with a plus or
minus, a string starting with the opposite sign is returned.
One effect of these rules is that -bareword is equivalent to
"-bareword".
