Thunks: Old-fashioned closures?

From: http://en.wiktionary.org/wiki/thunk

    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;

Certainly that's what Ingerman said to me.

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.
