[[!tag patch]]
As noted in the [[!cpan Try::Tiny]] man page, eval/$@ can be quite
awkward in corner cases, because $@ has the same properties and problems
as C's errno. While writing a regression test for definetemplate
in which it couldn't find an appropriate template, I received
Error: failed to process template
deftmpl
instead of the intended
Error: failed to process template
deftmpl template deftmpl not
found
which turned out to be because the "catch"-analogous block called
gettext before it used $@, and gettext can call define_gettext,
which uses eval.
Fixed in my branch smcv/ready/careful-eval. Another possibility
for fixing this would be to depend on something like Try::Tiny,
which is already indirectly recommended by ikiwiki, because
[[!cpan RPC::XML]], [[!cpan XML::Feed]], etc., depend on it.
