As a way of easing cross-platform scripting (prototyping system level software) is there a mechanism for implementing a Perl script that checks on what platform it is been executed and loads some certain modules that are that platform specific or execute some certain code for that platform(probably thought the use of a series of if like in c/c++:) 
#if defined __Linux__
...do something...
#elif defined __win32__
...do something.... )

I come from a C/C++ background and looking under the hood to learn Perl.
