Taylor Cramer	802a826a57	Stabilize static_recursion	2017-02-21 23:41:04 -08:00
Eli Friedman	0eea0f6e90	Allow writing types which "can't" be instantiated. ... The borrow checker doesn't allow constructing such a type at runtime using safe code, but there isn't any reason to ban them in the type checker. Included in this commit is an example of a neat static doubly-linked list. Feature-gated under the static_recursion gate to be on the safe side, but there are unlikely to be any reasons this shouldn't be turned on by default.	2015-07-24 19:18:16 -07:00
Eli Friedman	742e1242d9	Add static_recursion feature gate.	2015-07-24 19:17:58 -07:00
Eli Friedman	8ebf95257b	Allow recursive static variables. ... There isn't any particularly good reason for this restriction, so just get rid of it, and fix trans to handle this case.	2015-07-24 19:17:45 -07:00
