Okay, I'm confused, I thought one of the things you were trying to avoid was
having "noisy" names pulled into the templates for subsequent usage, so was
trying to avoid that totally.  However, if you're okay with the user having
to change stuff like UNTITLED_2_H, then why is changing TM1002022340_H
worse?  In either cases, it's a search and replace situation, no?
<p>
I'd have an easier time with just having the user delete the files in the
temp folder if it were easily accessible from Finder (or even Terminal), but
/var/folder/cT/cTlongtextgibberish/-Tmp-/ really isn't friendly to
user-access, period.  Heck I'd even be okay with just always deleting the
questionable file in -Tmp-, but that's hard in a template script precisely
because the untitled basename _does_ potentially change.  You kind of wind
up needing to know whether the basename was auto-generated or not to safely
make that call.  
<p>
BTW, that would be another workaround, just set an env var you hand to the
template building script set to 1 or 0 depending on whether basename was
auto-generated (file->new from template) or not.  Then templates know
they're in the -Tmp- dir, and thus whether they can overwrite any colliding
files "safely".
<p>
Since you've made your position clear, though, I'll drop it.  I look forward
to 2.0 when hopefully multi-file templates (very useful for C, C++ and Obj-C
"starter patterns") will be reliably useful.  Thanks again.
