[Swift-devel] Re: passing types and variables in swift

[Michael Wilde]

I should add:

While we discuss a direction here, I think that Andrew could do what he 
needs to do by just coding a script with statements like below.  As I 
recall Tibi and others have been doing this man many previous cases.

To make it manageable, he (or we) could do a simple ad-hoc #include 
mechanism to separate his core code from such list-setting code.

Andrew, can you take this from here using that approach?

Mihael: I think that addresses your "just say no" comment: do 
experiments that defer language changes until we see how they would be 
used and how best to couch them in the language.
