Correct. There is a needless space. However, this line was replaced by a simple statement in a later commit:
```open(...)```

Also, in the same file:
```eval "require $class";```
lacks error checking, but
```eval { require $class } or die "Could not load $class: $@\n";```
is wrong and never loads $class.
In a later commit, this became the best of both worlds:
```eval "require $class" or die "Could not load $class: $@\n";```
