- grammar.ebnf: the threadlocal keyword and the threadlocal binding form - concurrency.md: note that std.json/std.toml/std.io lean on threadlocal globals, which is what makes them safe to use from many tasks at once - limitations.md: the weak-field-read box leak is fixed for the common consumers (!= none / == none / .value()); only the indexed-collection read still synthesizes an unreclaimed optional - README: add std.env to the stdlib module list (it now has typed readers) performance.md already covers the freelist and connection pool; the grammar already documented numeric underscore separators, which now actually work.
