discrimination of constructors with same number of parameters

[sybrandy]

Why not have something like this:

this (int[] data, string text, bool isMessage = false) {...}

Then, if you just pass in two parameters you treat it as a filename and 
if you pass in a "true" for the third parameter, it's a message.  It's 
not quite what you're looking for, but it's simple and pretty clean.
