Hook::LexWrap allows you to install a pre- or post-wrapper (or both)
|
||
|
|
around an existing subroutine. Unlike other modules that provide this
|
||
|
|
capacity (e.g. Hook::PreAndPost and Hook::WrapSub), Hook::LexWrap
|
||
|
|
implements wrappers in such a way that the standard `caller' function
|
||
|
|
works correctly within the wrapped subroutine.
