Re: Checking on live site if subroutine exists

Just a minor comment about this pattern:

    my $_tsub = "SendMultiPartMemberEmailMimeLiteSendGrid";
    if(exists &{$_tsub}) {
        # code to call it
    } else {
        require "/path/to/the/file/SendMultiPartMemberEmailMimeLiteSen
+dGrid.pl";
        # code to call it
    }

Your code to call it is unnecessarily duplicated. Better:

    my $_tsub = "SendMultiPartMemberEmailMimeLiteSendGrid";
    if ( not exists &{$_tsub} ) {
        require "/path/to/the/file/SendMultiPartMemberEmailMimeLiteSen
+dGrid.pl";
    }
    # code to call it

But this can probably be even better written as:

    require "/path/to/the/file/SendMultiPartMemberEmailMimeLiteSendGri
+d.pl";
    # code to call it

Because require is smart enough to not load the same file twice.
