Actually I want to check the arguments' types before calling the 
appopriate (overloaded) C++ function. So, I want a check that 
'42' and '42.0' passes and a check that '42' only passes. So, if 
I have: 
 
foo (char *, double, double); 
foo (double, int, int); 
 
I can then call in ruby: 
 
foo 42, 20, 20 
foo 42.0, 20, 20 
foo "bar", 10, 1.2 
 
If this isn't supported by the Ruby API I will write my own C macro that 
will return true if TYPE == T_FLOAT || TYPE == T_FIXNUM.
