Or you can use Math::BigInt->new, because the odds of there being a BigInt sub in the Math package are astronomical :)

    The odds are small, yes. In my decade plus of Perl usage I've encountered bugs because of this two, perhaps three, times. But each time it took me bloody ages to figure out, which is why I have been trying to avoid this ambiguity in recent work.

    The aliased module is, by the way, an excellent way of avoiding these problems:

    use aliased 'Math::BigInt'; my $seven = BigInt->new(7); # no ambiguity
    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
