Of course not, but using eg "hfov" instead of "angle" means you don't even 
need to open the documentation to realise what it is setting.  It also then 
means the corresponding vfov could be used, again, without having to lookup 
in the documentation.  Once a language syntax gets more complex it's 
actually really handy to work like this, where most things are "obvious" 
without having to look up in the documentation each time.

...and I'm one of those weirdos who doesn't like needless inefficiencies, no 
matter how small :-)
