Case insensitive constants not supported

[chrisgraham]

'define' allows you to make case-insensitive constants, but hphp does not support this (it ignores the parameter).

As far as I'm concerned it's a horrid PHP feature so would be tempted just to document it as a an accepted difference in behaviour.

I would second documenting it as unsupported in HPHP. If horrid had an ugly little sister, case-insensitive constants would call her a bitch for being so hot.

I expect your take on this is going to be the case. It'd be pretty trivial under HHVM, but a PITA under HPHPc. Regardless of the implementation details, it is horrid's ugly little sibling and as such probably only worth of documenting under "differences from PHP".

I'm going to leave this open for now though, as it's worth keeping on the table.
