This is a second go at a module to simplify installing die() and warn()
|
||
|
handlers, and to make such handlers easier to write and control.

|
For most people, this just means that if use use Religion; then you'll get

||
|
noticably better error reporting from warn() and die(). This is especially
|
||
|
useful if you are using eval().

|
|
||
|
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
|
||
|
situation, and provide information about where you were, which might

||
|
influence where you want to go next, either returning back to where
