True, it could, but it would be odd that what looks like assignment
and an expression is actually magical syntax. But it might be nice to
have something that functions as lambda currently does, unless it
detects that it's being assigned directly to a name, in which case the
magic kicks in and it gets a name.
square = x->x**2 # Name is "square"
operator["square"] = x->x**2 # Maybe?
create_operator("square", x->x**2) # Name is "<lambda>"
But I suspect that this would create some hairy grammatical quirks.
Still, as an "alternate syntax for creating a lambda function", it
seems at least plausible.
