| You're confusing static typing and strong typing.

| In a weakly-typed language, like C, it is possible to cast an integer
| as a, for instance, a char*, and then call string functions like
| sprintf() on it and the compiler will compile it, the runtime will run
| it, and it will wreak whatever havoc you please.  Most high-level
| languages are strongly-typed, these days - neither Java or Ruby will
| allow you to call a String method on an Integer.  You can assign
| whatever object you want to a variable in Ruby - hence *dynamic*
| typing - but that object will only ever allow you to call supported
| methods on it; otherwise you'll get a NoMethodError.  Hence *strong*
| typing.

Thanks for the enlightenment. :)
