Re: Token filter for erlang-style numbers.

[Asko Kauppi <askok@...>]

tab={}
tab[ MY_GUI_EVENT ]= do my_event_handling_code end

For just calling blah() one would obviously not use/need/benefit from  
this.

Or:
switch( cond ) {
	['a']= do ..cmds for a.. end,
	['b']= do ..cmds for b.. end,
}

The switch implementation is just a Lua function (ask if interested,  
not really relevant here)
