Request for inline control of warning level

[Simon Peyton-Jones]

| OPTIONS_GHC pragmas allow warnings to be enabled or disabled for a
| particular file, but there are some limitations:
|
|  * It doesn't override command-line settings (being tacked on the start,
| rather than the end, of the options lists, I believe)

I don't think this is right -- or if it is, it's a bug.  The OPTIONS_GHC stuff is supposed to override command-line opts

|  * It doesn't work on sections of the code, but rather the whole file.

True, and it'd be great to give more local pragma control -- a good feature request.  Someone might want to work out details of the programmer's eye view and make a Trac feature request
