But the OP isn't suggesting default values. See, for example, his
discussion of ignoring any errors when the user doesn't supply a
parameter to a function. If all he wanted was a default value, we can
do that already.

Of course you can already do this:
var[index:index+1] or [default]
if var is a list, and
if it is a dictionary.
