in reply to Nested evals - are they evil?

Is all the use of eval/checking as gratuitous as the above - just calling confess to die with a backtrace?

You might be able to install Carp's confess method as your fatal error handler. Then you can eliminate the evals and checking code.

#!/usr/bin/perl # # Die with backtrace # use Carp; $SIG{__DIE__} = \&Carp::confess; callMethod(); sub callMethod { # blah blah someMethod(0); } Sub someMethod { 1/shift; }
Alternatively, you can set up local handlers and eliminate evals, on a case-by-case basis:
sub callMethod { local $SIG{__DIE__} = sub {confess ("error calling someMethod: $_[0] +")}; someMethod(0); }
