Thunks: Old-fashioned closures?

From: <a href="http://en.wiktionary.org/wiki/thunk" rel="nofollow">http://en.wiktionary.org/wiki/thunk</a><p><pre><code> Claimed by the inventors to be from the supposed past tense, being coined when they realised after much thought (whence "thunk") that the type of an argument in ALGOL 60 could be predetermined at compile time; </code></pre> Certainly that's what Ingerman said to me.<p>Related to this, I'm finding myself using "Lunk," "Cluck," and "Drug" as the past tense versions of "Link", "Click" and "Drag". They're easier to say, and most people seem to understand without effort.

In the Lisp 'world' a thunk is often a function/closure with no parameters.
