Zach Laine
54d1b14237 Wrap the first argument to transform() by calling as_expr() on it, so that 
as_expr() is rarely needed outside of transform().

Continue to accept rvalue transform objects in the top-level transform(), but
do not perfectly forward it into the implementation details of transform().
This fixes the potential bug of stealing the movable contents of a transform.

Simplify the implementation of transform() considerably.

Fixes #62.
