This is not specific to `import`; it works with all class method calls... `use Math::BigInt; my $class = "Math::BigInt"; my $six = $class->new(6); my $seven = "Math::BigInt"->new(7); my $eight = join("::", "Math", "BigInt")->new(8);` [download] In fact, string quoting class names is arguably a much better idea than the more conventional `Math::BigInt->new(9)`, because the latter will start behaving surprisingly if there's ever a `BigInt` sub defined in the `Math` package. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l] [select]

Indeed. This has the (often welcome) side-effect that the existence of the package is checked at compile-time, and a warning is issued (if warnings are enabled) if the package does not exist. With stringy class names (and indeed with the traditional `Foo::Bar->new`) there is no such check, and Perl just blows up when it can't resolve the method call. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l]

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

Do you know where your variables are?
