Thanks for the very clear explanation.  Makes sense now.

The best workaround I've thought of so far is to use an identity 
function to change an expression into an acceptable form for a `:',
like this

    m3 = I(m1 * m2):invert()

where I is 

    function I(arg) return arg; end

Anyway, it avoids having to assign sub-expressions to temporary 
variables.
