rustc: Implement "mutable?". Add a test case and XFAIL it in rustboot for now. 2011-03-18 13:49:06 -05:00
Reformat source tree (minus a couple tests that are still grumpy). 2011-06-15 13:19:50 -05:00

rustc: Accept 'const' as synonym for 'mutable?' 2011-11-16 15:52:08 -06:00			`fn len(v: [const int]) -> uint {`
make --enforce-mut-vars always on, add mut annotations to remaining files 2012-03-22 10:39:41 -05:00			`let mut i = 0u;`
Convert old-style for loops to new-style Most could use the each method, but because of the hack used to disambiguate old- and new-style loops, some had to use vec::each. (This hack will go away soon.) Issue #1619 2012-04-06 13:01:43 -05:00			`for v.each {\|x\| i += 1u; }`

Reformat This changes the indexing syntax from .() to [], the vector syntax from ~[] to [] and the extension syntax from #fmt() to #fmt[] 2011-08-19 17:16:48 -05:00			`let v0 = [1, 2, 3, 4, 5];`
Register new snapshots, purge log_err and log_full in favour of log(...). 2011-12-22 19:53:53 -06:00			`log(debug, len(v0));`
Bulk-edit mutable -> mut. 2012-03-26 20:35:18 -05:00			`let v1 = [mut 1, 2, 3, 4, 5];`

The wonky for...in... whitespace was bothering me. Sorry! 2011-08-15 23:54:52 -05:00			`}`
