I suppose it's better to always normalize a polymorphic string
representation. And always normalize bignums to fixnums (long->int).
It increases chances of using the more compact representation.
It doesn't add any asymptotic cost, it's done when the whole
object is to be allocated anyway (these are immutable objects).
It simplifies equality comparison.
The narrow formats should be statistically more common than wide
formats anyway.
Programmers should not be expected to care about explicitly calling
a normalization function.
