Editorial: difference between "well defined" and "well-defined"?

[mclow]

The standard uses 'well defined' in 7 different places.
It uses "well-defined" (with a hyphen) in 64 places.

A quick look at the seven suggests that most of them could be replaced with 'well-defined', increasing the consistency of the standard.

According to #1587, it’s supposed to be hyphenated when it’s an adjective. The grammar is slightly different in the cases without a hyphen.

If the difference is intentional, then this can be closed as NAD. I just want to make searching the standard easier ;-)

[tkoeppe]

The style guide says that "well-defined" is the way to spell the adjective. The new cases of "well defined" seem to have come in via recent motions; I assume LWG reviewed those before we added the style guide entry.

Duplicate of #1618.

Uh, sorry, #1618 is about well-formed, this issue is about well-defined.
