Signature surveys

Jim Weirich writes on stripping out the text from a program, leaving only the "line noise" (punctuation). He notes:

What I find interesting is the amount of semantic information that still comes through the "line noise". For example, the "#<>" sequence in the C++ code is obviously an include statement for something in the standard library and the "<<" are output statements using "cout".

That reminds me of something that Ward Cunningham described. He called them "signature surveys". It's a really sweet idea, even more impressive when you see him demo it.
