Load or reload a Perl module. This is like I<require> with a file |
39
|
|
|
|
|
|
|
name, but we force the load or reload. Use this if you change the Perl |
40
|
|
|
|
|
|
|
module while you are debugging and it want those changes to take |
41
|
|
|
|
|
|
|
effect in both the debugged program and inside the debugger. |

Note however that any functions along the call stack will not be |
44
|
|
|
|
|
|
|
changed. |
