Questions and comments about the Architecture paper

[John Levon]

I assume that to access function arguments, you can just use the name of
the argument in the source, since systemtap operates based on the dwarf2
debug info?  How do I refer to an anonymous return value?

Why isn't switch() supported?

Since I don't have struct.field or structp->field, how do I traverse a
structure? (Same goes for sizeof()).

thanks,
