|
Religion provides four classes, WarnHandler, DieHandler, WarnPreHandler, and

|
DiePreHandler, that when you construct them return closures that can be
|
|
stored in variables that in turn get invoked by $SIG{__DIE__} and
|
|
$SIG{__WARN__}. Note that if Religion is in use, you should not modify
|
|
$SIG{__DIE__} or $SIG{__WARN__}, unless you are careful about invoking
|
|
chaining to the old handler.

|
|
Religion also provides a TraceBack function, which is used by a DieHandler
|
|
after you die() to give a better handle on the current scope of your
