Re: D-styled data file

[Saaa]

I changed the prototype to:

void get(in char[] varName, ...)

I'm not totally happy with it because I only need one variadic argument and 
:

How do I get the .stringof of an variadic type?
_arguments[0].stringof doesn't work :)

How do I mutate the original argument? (ref)

Please tell me if I'm on the totally wrong track here.
