Personally, I would strongly prefer the caller syntax my_func('a',
'b', 'c' => 'd', $e => $f) just to because
1) it's consistent with array declaration syntax
2) it allows arbitrary names for parameters, which will become the
array keys ... and can include funny characters
3) naked identifiers in PHP are used only for functions, classes and
constants, so c => 'd' looks like a constant
4) it allows the flexibility of dynamically specifying parameter
names, although this will probably be rarely needed
My second favorite is my_func('a', 'b', c => 'd') ... which I consider
worse but at least not as bad as my_func('a', 'b', c: 'd') ... which
seems to come out of left field as it's not consistent with the rest
of PHP syntax. Unless, of course, c: 'd' is going to be a shorthand
for 'c' => 'd' ... which makes me ask ... if you guys are ever going
to make a short array declaration syntax, will it look something like
this: {'a'=>'b', 'c'=>'d'} or will it look like {a: 'b', c: 'd'} ?
Anyway, my 2c.
