No no, I didn't say that you can't keep T_Integer and T_Float nodes
separate.  I was just suggesting that the *value* of one of these nodes
might be kept as a string (or, perhaps, both as a string and the numeric
format).  That way, if you need to convert to some other type, you start
from the original string and don't have to risk a "lossy compression"
into floating point.
