Re: [betwixt] Using interfaces as property types/ in collect

[Sandor Murakozi <sa...@freemail.hu>]

hi robert,

I use the source that can be downloaded as daily build. 
Unfortunately I'm behind an "uber-secure" firewall, so I
can't acces the rep. directly. I know that I could use
CVSGrab, or something, but it was easier. I guess it is the
HEAD, but you know it better...

BR,
don

that's the HEAD version. the version on the REFACTORING has had a lot 
of work done on it and IIRC some in this area.

if you can wait a few days, once the release branch is taken for 0.5 
the REFACTORING branch will be merged into HEAD. so, the stuff on HEAD 
will contain the improvements from the branch.

if you can't wait, then i'd suggest using CVSGrab to grab the source 
for the branch and build that instead.
