True, although there are other examples where the first parameter is by no 
means obvious:

GtkHBox new: true spacing: 3.

In this case, the first parameter is homogeneous, but

GtkHBox newHomogeneous: true spacing: 3.

is a pain to type, so I'm still in favour of the shorter scheme.

I like that a lot - you're proposing it as a convenience method, though, 
presumably?

There's a big need for convenience methods, for writing new code in Smalltalk, 
although I also think that being able to translate already-written Gtk programs 
from C into Smalltalk with as little fuss as possible is a very worthwhile aim. 
If nothing else, so that people can take advantage of the pre-existing Gtk 
tutorials.
