Tastes are different.
As you may have noticed
(a) I am not too big a fan of any boost in headers, not to speak of
something as crucial as lyxtext.h and
(b) the y parameter used to be passed by ref already, so this is
no invention of mine.
I admit that I don't like the mix of return value and ref arg, but as I
said: not my doing, and if somebody introduces boost in lyxtext.h it
certainly won't be me.
