Hi.

Would it be possible to have a new magic method allowing a class to 
handle a request for a constant that has not been defined.

<?php
class ANSI {
 static public function __constant($constant) {
  // Parse $constant to determine response.
  // e.g. turning COLOUR_BRIGHT_FG_WHITE_RED
  // into '1;37;41';
 }
}

The values for various constant names are constant. They won't change, 
but having to manually create all the combinations is a headache. They 
could be cached internally. So asking for a constant and not finding 
it would allow the magic method to run and then save it for the next 
usage. Maybe. Or not.

I know this is easily handled as ...

ANSI::convertConstantStringToANSISequence(COLOUR_BRIGHT_FG_WHITE_RED)

but 

ANSI::COLOUR_BRIGHT_FG_WHITE_RED

is the intent.

Even without the caching (which could be done in userland if constants 
could be added at runtime), then this would be useful.

Any takers?
