Re: Combining Tolog and path expressions

I like this idea, and think it is worth pursuing. (Anyone interested
in the detail of what Dmitry and I discussed can look at the IRC
channel logs[1].)
 
| One of the discussed syntaxes:
| 
| <topic variable>[<type expression>;<conditions with simple paths>]

Here I think the <type expression> should be merged with other types
of conditions, since there seems little reason to consider it a
different kind of thing.

In general I like the idea, though. The main thing missing seems to be
a consistent syntax and model for the path expressions that fits into
the existing language. Something can probably be found, but I don't
feel that it's happened yet.
