(One pre-requisite for this would be to finally ban the use of "=" as standing in for "==", otherwise it's next to impossible I guess.)
On the other hand, maybe the "=" itself would already be enough to signal to the parser that it's a name:
myfunc(a=5)
This of course is basically like it's done in Python (and other languages).

I reckon that's the best way to go: an identifier directly followed by a single equals sign in an argument slot should be enough to designate uniquely a named-parameter construct.

I'm not yet convinced this is worthwhile (I can see the benefit but I'm not sure it outweighs the cost), but I'm willing to be persuaded.
