--- Comment #1 from David Cook <[email protected]> ---
On https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=39740#c74 I ask:

"Move export to do_instance, remove three local's"

Marcel, do you recall why you removed those locals? Because they were
important.

--

The thing is... "export PERL5LIB KOHA_HOME GIT_INSTALL" really doesn't need to
be in _do_instance(). The "export" simply marks those variables as being
exported. It has nothing to do with their values.

Sometimes, we do things like 'export PERL5OPT="-d"' which is just a short-hand
of 'export PERL5OPT; PERL5OPT="-d";'. But that's not what the above does.

So it was fine where it was previously. Running "export PERL5LIB KOHA_HOME
GIT_INSTALL" in _do_instance() is just needless repetition.

--

And the problem with removing the "local" keyword is that it means these
variables are used globally, so KOHA_HOME and GIT_INSTALL will overwrite
previous values, while PERL5LIB just grows and grows, as I describe in bug
25778.
