snafu, I fear you have stumbled onto a series of incantions that appear to work, but that you still do not understand the underlying problem. Consider:
eval {join(',', @args), return(@args)}
has the same affect as
eval {return(@args)}
since the join() has no side-effect. In turn, these have the same effect as
eval {@args}
and
@args
The execute() method wants distinct arguments ie
execute(arg1,arg2,arg3) vs execute(qw(arg1,arg2,arg3)) which is the same, of course, as execute(@args).
if @args hold (1,2,3), then
- execute(1,2,3);
- execute(qw(1 2 3));
- execute(@args)
are equivalent, but
is
not equivalent, since
qw(1,2,3) is an list that contains a single element. It's the whitespace that's significant in qw(), not the commas.
