Comment(by maeder):
It does not even need an undecidable type system for compilation to fail.
The following source is enough:
{{{
main = print 1E1000000000
}}}
Using Rational or Integer is a bad idea to compute the exponent factor
(with "^" or "^^"), in particular since the exponent notation is not
supported for these types.
