Builtin rules

[Simon Peyton-Jones]

No, it's a bug.  Don't convert source rules to builtin ones!
I'll look at it when I get back (week of 30th)

| When there is a builtin rule and a source rule on the same variable,
| the builtin rule seems to be ignored.
|=20
| For example there is a builtin rule for int2Word# applied to literals
| and a source rule for int2Word# (word2Int# x#), and int2Word# applied
| to literals is not computed at compile time.
|=20
| Is it a bug (in this case it should be fixed), or it should indeed
| work that way (in this case I will convert some source rules into
| builtin rules and add some rules as builtin rules instead of as
| source rules, e.g. x# <=3D# x# =3D True, to ensure that no variable =
has
| both kinds of rules)?
