Actually, getfenv and setfenv will be deprecated too. (But is is easy
to have them back for compatibility.)
Lua 5.2 will have "lexical environments", a kind of lexical setfenv.
The construction "in t do command end" will execute <command> with
all global variables being resolved in <t>.
Modules can be written as "in module(...) do <body> end", with the
module function returning the module table.
lua_getfenv and lua_setfenv will continue, as debug.setfenv and
debug.getfenv.
