Why a Capital F class functions?

I was starting to use sublime text as an editor with ctags plugin and I noticed the functions of your class were not recognized as functions and neither by the ctags function.

I understand this is completely off-topic to the function of the class, but why the capital F in "F"unction definitions? I was hoping to have a setting to allow both the editor and ctags to allow this keyword but they are not nicely working so far, was it a personal preference or a reason out of it.

This is just out of curiosity, thanks.

This is my programming style since I ever started programming with PHP in 1997, even before PHP had classes.

Anyway, it is just a convention that makes the code more readable to me.

In PHP function names are case insensitive, so it should not matter, except probably for ctags I guess.

Aha, sublime text doesn't like "Function" either although I would probably think that beast should be configurable for that.

Thanks! have another more implementation related question to you on another thread.
