Do you have coverity scan of perl/Tk?
Show me

Did you ever looked into perl/Tk source tree?
Its a mess. First file that now I looked at, the file './VERSIONS' in perl/Tk-804.027 say

This is Tk402.001

The name by the way is Tcl/Tk's 4.2 with three digits for me to mess w
+ith.

I hope Sun don't get through more than 100 revisions so two sub-versio
+n digits
will be enough for them.

I will subsume Sun's 'patch' stuff (e.g. '3' in 4.2p2) into my digits 
+as we have
tended  to be 'ahead' of them on some fixes and behind on others so we
+ don't
map exactly at that level.

For my digits I will use the 'even'=stable, 'odd'='experimental'
scheme that linux uses:

 .0xx  - inherently 'alpha'
 .1xx  - experimental 'beta'
 .2xx  - stable
 .3xx  - experimental
 .4xx  - stable

There are *many* such examples, just scratching the surface.

Do you think entire perl/Tk distribution is smooth and Coverity scan will be smooth??

About "perl/Tk language feels very perlish" - I agree.
Tcl::Tk supports perl/Tk syntax. So TIMTOWTDI is wider in Tcl::Tk, thus Tcl::Tk is even more perlish :):)
