The thing is php needs to be able to "lexify" raw input data at runtime, while 
in D this is done at compile-time. The ompiler has the lexer to do that.

But I agree that, for user input, it would be cool to have such a feature 
available. However, this would quickly become complex because of (the reciprocal 
of) localisation, or even personalisation. Eg I like to write decimals like:
	-1'234'457,098
