|No such thing as a small change|
unless your module is broken, of course
This is of course a grave concern. I am fairly confident that it is not too broken and somewhat reassured that it runs the CGI.pm test suite as well as a large number of unit tests. I wrote unit tests (well actually I wrote a perl script that wrote stubs for most of them) for every function in void, scalar and array context so the test suite is extensive.
I have checked the install under Win95, 98 and NT and Linux Redhat and Mandrake and FreeBSD and it installs fine.
Despite this any QA specialist will tell you there is always another bug, indeed Ovid has already found a blatant one (under mod_perl). I am hopeful that some of the monks who run development servers may consider the speed benefit worthwhile to experiment with it. It is only through widespread testing that you can truly start to feel confident that a piece of software is really stable.
