I very often want something like a try-except conditional expression similar
to the if-else conditional.
An example of the proposed syntax might be:
x = float(string) except float('nan')
or possibly
x = float(string) except ValueError float('nan')
+1 I've long wanted something like this.
One possible spelling is:
x = float(string) except ValueError else float('nan')
I think 'as' would be better than 'else', since 'else' has a
different meaning in try/except statements, e.g.:
x = float(string) except ValueError, TypeError as float('nan')
Of course, this is a different meaning of 'as', too, but it's not
"as" contradictory, IMO... ;-)
