Change option::t to option Now that core exports "option" as a synonym for option::t, search-and- replace option::t with option. The only place that still refers to option::t are the modules in libcore that use option, because fixing this requires a new snapshot (forthcoming). 2012-01-31 19:05:20 -06:00			`fn f<T>(&o: option<T>) {`

change the test suite `//! kind` syntax to `//~ kind` in order to avoid a conflict with the new single-line-sugared-inner-doc-comment (`//! ...`). 2012-06-30 06:23:59 -05:00			`//~^ ERROR taking mut reference to static item`
Fix #2979: inference for lifetimes of & expressions What we now do is to create a region variable for each & expression (and also each borrow). The lifetime of this variable will be checked by borrowck to ensure it is not greater than the lifetime of the underlying data. This both leads to shorter lifetimes in some cases but also longer in others, such as taking the address to the interior of unique boxes tht are rooted in region pointers (e.g., returning a pointer to the interior of a sendable map). This may lead to issue #2977 if the rvalue is not POD, because we may drop the data in trans sooner than borrowck expects us to. Need to work out precisely where that fix ought to occur. 2012-07-26 10:51:57 -05:00			`//~^^ ERROR illegal borrow: creating mutable alias to aliasable, immutable memory`
