I'm more or less indifferent to this feature request, but if implemented it won't stop the "locals blocks" completely for the following reasons:
* Compatibility. Lua 5.1 and 5.2 don't have it, so I probably won't use it until those version become more or less insignificant (or I'm depending on the newest Lua version anyway). * I prefer my localized standard functions to have a prefix (like `t_concat`), because locals like `len`, `insert`, `remove` (already ambiguous), date, time, find, match, sub, byte, etc. are likely to appear in my own code. The namespace is an important part of the function's name, IMHO. * I prefer to make sure that the field I requested is really there (using e.g. `local t_concat = assert( table.concat )`).
I guess the last two points are very specific to me, but the compatibility argument will probably be valid for other Lua users as well ...
