The aim of the wrapt module is to provide a transparent object proxy
for Python, which can be used as the basis for the construction of function
wrappers and decorator functions.
The wrapt module focuses very much on correctness. It therefore goes
way beyond existing mechanisms such as
functools.wraps() to ensure that
decorators preserve introspectability, signatures, type checking abilities
etc. The decorators that can be constructed using this module will work in
far more scenarios than typical decorators and provide more predictable and
To ensure that the overhead is as minimal as possible, a C extension module
is used for performance critical components. An automatic fallback to a
pure Python implementation is also provided where a target system does not
have a compiler to allow the C extension to be compiled.
