The context is general knowledge. This all started when I read the passage I tersely quoted and blakem included in full. It's not to solve a specific implementation problem, but rather to ensure understanding so that I can avoid specific implementation problems.

I can't figure out why you would ever want to execute/eval untainted CGI input as-is

Yeah, that does sound dangerous. That's why the quoted material caught my attention. It seemes to imply that code could be evaluated without my express permission but instead simply because I put it in double quotes. That kinda freaked me out.
