Hello bf3,

i guess because it makes type inference problematic. imagine 10
overloaded functions used together:

func = a.b.c.d.e.f.g.h.i.j

it will create 2^10 variants to check and make error messages very
verbose (or non-informative). with type classes, you give common name
to all the type variants you want to overload. at least, this
simplifies error messages :)
