I'm not clear what this has to do with case sensitivity; the problem here =
is that we don't have a type of "function reference" (nor "class reference"=
) so simulate such references with strings and runtime assertions=2E

Are you saying that without case sensitivity, the language could deduce th=
at sum2 in that case was a function reference? That seems optimistic: not o=
nly can you have a class, a constant, and a function all with the same name=
, but you can't actually know which exists until the line is executed, beca=
use all three can be defined at any time=2E

This kind of ambiguous syntax is precisely what I was trying to reduce by =
deprecating "undefined constant as string", and a similar "convenient fallb=
ack" (from current to global namespace) is currently the biggest thing bloc=
king function autoloading=2E

If we want function and class references, they should have their own, unam=
biguous, syntax=2E

Apologies if I've completely missed the point here=2E
