No, there are multiple IDEs that support it to some extend or the other.
XCode, Eclipse has had plugins in the past, Emacs (if you can find the
editor in that OS)

It's only important in ease of use and shorthand cases. If it really is
functionality that is not doable otherwise, it's a different matter.  Nobody
will argue that a template that generates a wrapper around a container class
is a substitute for generics.

IOW, for this argument, the only advantage in favour must be shorthand, or
other editing work related speedup of workflow.

I don't believe in adding shorthands solely based on such reasons. THat is a
carte blanche for all kinds of char twiddling non improvmeents.

And in this case IMHO it is a specialisation of CASE, which is already an
specialization of nested if then.

If we implement that, we'll get the next level of specialization within the
year probably, and probablyagain with similar argumentation
