in reply to Pre-populating <STDIN> with a default value

[Corion]: GotToBTru: Yeah, I started a quick(ly implemented but slowly running) implementation of a program that would guess the "best" configuration (that is, least amount of changes) from my code, but then found that it stops parsing the source as soon as it ..

[Corion]: GotToBTru: Yeah, that stuff is hard to do away automatically ;)
[GotToBTru]: yeah, you mentioned it could not handle signatures
