For an open-source project that I'm working on (1), which uses R for

http://github.com/hadley/eval.with.details. As you might guess, it's
a version of eval that captures all details like messages, warnings,
errors and output so you can do

Many thanks for your responses. The eval.with.details package sounds
interesting and I'll certainly take a closer look, but it still seems
to me that these approaches are focussed on trapping warnings within
specific snippets of code rather than changing the way all warnings
