This is not currently possible, and I am ambivalent about the idea. The problem
with this
kind of default is that it leads to syntactic confusion which can lead to
errors. I like
the discipline of always typing the value you intend, because it is this
intention that
should be made clear.
Also, missing out parameters only works if there is one, or if it is the last
of a list,
otherwise the prototype correspondence gets broken. I think the ambiguity is
potentially
too dangerous for a mission critical application.
