Thanks for pointing out about the general term. Although the majority of the general form is for require/use, people do use it for other purposes too:

I wish the grep.cpan.me supported lookaheads and lookbehinds, which would allow me to search a little more specifically for situations where the idiom is used outside of the "require" and "use" use case. If it did, I might try something like: `if \(eval ["'](?!require\|use).+?;\s*1;?["']` [download] Dave	[reply] [d/l]

I wish the grep.cpan.me supported lookaheads and lookbehinds We can use `[^ur]` as a cheap trick to grep for cases other than `use` or `require`: `(if\|unless) \(eval +["'][^ru].+?; 1;?["']`	[reply] [d/l] [select]
