lazy composition : concatenative vs. compositional

I'm not using the concatenative vs. compositional property anywhere.
This extra inspection level could be useful for optimizations.  It
boils down to 'lazy composition'.

Bottom line: hiding the primary composition mechanism behind lambda is
NOT a good idea because it throws away information that might be
exploited during optimization.  The lambda representation IS a good
idea for introducing arbitrary primitives however.

The good part is that this is easy to change.

Also note that a CPS style representation is actually better than a
nested lambda expression representation.
