I admit I'd opt for inconsistency over further punctuation in this
case :-) But actually I'm not sure I'd agree that & in arglists is the
same usage as & as synonym for lambda.  I've always thought of it as a
kind of singular construct, necessary because the whole code-block
thing has that singularity.  Also there's this:

  pr = lambda {}
  some_method &pr

which would become

  pr = &{}
  some_method &pr

which bugs me in some way involving levels of indirection that I can't
quite put my finger on....
