It'd be great if this were a standard feature you can also use for your own objects. I believe $foo.Num in this case should return the Num-ified version of $foo. And maybe the int method numbers have is redundant, and should be spelled Int instead. Or, well, if this is the case, int should return an int (not Int) for consistency. Maybe +$foo even maps to $foo.Num, and ~$foo maps to $foo.Str and ?$foo maps to $foo.Bool? Hm, are charsets representable as classes/roles? my Str::utf8 $bar = ...; my Str::latin1 $foo = $bar; Juerd -- http://convolution.nl/maak_juerd_blij.html http://convolution.nl/make_juerd_happy.html http://convolution.nl/gajigu_juerd_n.html
