Lambda Example Generation Tool

[Stephen Colebourne]

I played with this and found it useful, although I think the best
option families are already under discussion.

If anyone wants a copy of my syntax and/or generated files (which I've
enhanced to enable the simplifed-strawman alternative), email me
PRIVATELY.
