Yes, and Tcl being a multiplatform language has sometimes inside the programas 
this one does a test on which OS is running and act accordingly.
I also hope maintainers take a look soon. In fact, it seems that in an 
earlierrelease of the package the move to use the defautl interpreter was 
commented but for some reason didn't see it performed in the releases for 
Ubuntu up to the version I tested.

Subject: [Bug 1921803] Re: visual-regexp fails to start complaining “wish8.5” 
not found

>W.r.t. use of apport, there could not be anything in apport as the
application didn't start at all, isn't it?

Whether or not the application starts, ubuntu-bug still adds information
based on the package. I pulled up a random example, if you take a look
at the last section in bug 1558370, that's automatically added info on
package version, the Ubuntu release and architecture. (Fair enough, for
an interpreted language the CPU architecture often doesn't matter, but
there are cases where some bugs only happen on certain hardware and it
is not possible to reproduce elsewhere).

In this case, it's pretty straight forward to recreate. (And the
suggested solution looks good, I hope the maintainers will take a look
at it soon :) ) But there are cases where it helps with the additional
information to tell if the bug might have been fixed in a newer release,
or if I'm missing something.

Title:
  visual-regexp fails to start complaining “wish8.5” not found

Status in visual-regexp package in Ubuntu:
  Confirmed

Bug description:
  The Tcl file visual-regexp installed at /usr/bin has the interpreter
  “wish8.5” hard coded in the shebang line.

  However newer versions of Tcl have wish8.6 installed.

  A solution would be to remove the specific version on the shebang line
  leaving only "wish" as the installation of Tcl automatically creates a
  link to the correct version of wish.

  Presently the possibility of having too earlier versions of wish in a
  machine are remote, so just this correction should sufice.

  If it is deemed a more conservative approach should be used, then the
  mechanisms of checking the interpreter version could be put at the
  very start of the program.
