I think that IronPython does the same as the .Net runtime does. Look
at boo's output:

$ booish
Welcome to booish, an interpreter for the boo programming language.

Running boo 0.7.5.2013.

The following builtin functions are available:
    dir(Type): lists the members of a type
    help(Type): prints detailed information about a type
    load(string): evals an external boo file
    globals(): returns the names of all variables known to the interpreter

Enter boo code in the prompt below.
>>> 10**100
1E+100
>>> 10**1000000
∞
>>> 10**735293857239475
ERROR: Error reading from 'input3': 'Value too large or too small.'.
>>> (10**100).GetType()
System.Double

Well, it's a double on boo instead of a very long int as in Python. I
don't know if in IronPython it's the same.
