I am looking for a convenient and reliable method to customize errors and warnings autogenerated by perl, things like: 

use of uninitialized variable in ...
undefined subroutine ... called at ...
can't use string("") as a HASH ref ...

I just want to be able to customize these messages by prepending a timestamp .. something like this would be ideal 

use Error::Customize;

$customize = sub {
  return $makeatimestamp->() . $_[0];
};

[download]

I could probably hack this together with __WARN__ and __DIE__ handlers, but I'm sure there's some gotcha's, and someone must have done this before.
