Sometimes one wants to unpack values of two similar (or the same) types in a local scope and then variable names clash. A typical example is implementing an operator or some types, eg

function Base.==(x::MyAB, y::MyAB)
    x.a == y.a && x.b == y.b
end

Cf common-lisp:with-slots. I wonder if there is some syntax we could co-opt for this purpose.

Add support for renamed local variables.
0a820c8 
Fixes mauro3#18.

Incidental changes:

- wrap some tests into testsets, so that we can use `@isdefined` in tests

- add more validation of input expressions, test for expressions that
  are invalid but were expanded and failed with an obscure error message
