+
+As noted in the 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
+
+ <span class="error">Error: failed to process template
+ <span class="createlink">deftmpl</span> </span>
+
+instead of the intended
+
+ <span class="error">Error: failed to process template
+ <span class="createlink">deftmpl</span> template deftmpl not
+ found</span>
+
+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. --[[smcv]]
