The author must have done this for some reason... Because in the real code, unlike your simplification of it, the weakened sub reference forms a closure over itself:
Ie. It contains a circular reference which would leak memory without the weakening. For example, with the weaken commented, this leaks like a sieve:
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
In reply to Re^3: What's the weaken here for?
