I think type conversion shouldn't be done internally, implicitly.
Implicit conversion leads more confusion in the language. when you pass
variables, you have to remember these conversion rules.
type conversion should be done in the caller, that's why typed language
like C or C++ ask you to convert the type manually before you pass the
variable into a function.
