I now appreciate that line noise is harder on the fingers in Europe ;)

A keyword 'lambda' would in fact be easier to type and any decent
editor expands abbreviations.

Does lambda x,y (x*(x+y)) feel unbalanced?  In its favour, it does
make _longer_ expressions more visible

 lambda x,y,z (x+(x-2)*g(x,y,z-2*(x+y))-y*z)

(I have a strong urge to put parens around the formal arg list ;))
