Well, that helps a bit with the implementation, but doesn't solve the fundamental problem of having to handle the non-blessed case. Also, you now have to pull in another module to check for blessedness.

    You could always use some sort of object wrapper to convert the strings into error objects, and hide that in the 'try' code,

    local $_ = (blessed $@) ? $@ : MyStringErrorClass->new($@);
    or some such. That class (or a function that returns different error objects depending on the error string, or something), would know all about the Errno module, and other standard kinds of errors.
