load module {Perl-module-file}
Load or reload a Perl module. This is like require with a file name, but we force the load or reload. Use this if you change the Perl module while you are debugging and it want those changes to take effect in both the debugged program and inside the debugger.
Note however that any functions along the call stack will not be changed.
