Vararg functions with vararg tables don't use the arguments hidden in
the stack; therfore, it doesn't need to build/keep them.
New conceptual model for vararg2025-11-26T14:18:29+00:00Roberto Iroberto@inf.puc-rio.br2025-11-26T14:18:29+00:00urn:sha1:f33cc4ddec886ea499d7d41dd60cac5ddc5687db
Conceptually, all functions get their vararg arguments in a vararg
table. The storing of vararg arguments in the stack is always treated
as an optimization.

'__pairs' can also return a to-be-closed object2025-11-11T18:11:06+00:00Roberto Iroberto@inf.puc-rio.br2025-11-11T18:11:06+00:00urn:sha1:4cf498210e6a60637a7abb06d32460ec21efdbdcExternal strings are as good as internal ones2025-11-11T17:40:30+00:00Roberto Iroberto@inf.puc-rio.br2025-11-11T17:40:30+00:00urn:sha1:5b7d9987642f72d44223a8e5e79e013bb2b3d579
A '__mode' metafield and an "n" key both can be external strings.
Correction in line info for semantic errors2025-11-11T17:36:16+00:00Roberto Iroberto@inf.puc-rio.br2025-11-11T17:36:16+00:00urn:sha1:81f4def54f440e045b1401f11ef78b65b56b7abe
Semantic errors should refer the last used token, not the next one.
Global initialization checks name conflict2025-11-08T14:43:42+00:00Roberto Iroberto@inf.puc-rio.br2025-11-08T14:43:42+00:00urn:sha1:e44f3a2ffc7ced5e75cca7657aaa60ef27da89aa
Initialization "global a = 10" raises an error if global 'a' is already
defined, that is, it has a non-nil value.
Vertical bar removed from syntax of vararg table2025-10-30T14:07:01+00:00Roberto Iroberto@inf.puc-rio.br2025-10-30T14:07:01+00:00urn:sha1:d342328e5b24c9b3c6c5b33bfcf9f8534210b8e6
The syntax 'function foo (a, b, ...arg)' is already used by JavaScript
for this same semantics, so it seems natural to use the same notation in
Lua.
Case VVARGIND added to luaK_storevar2025-10-30T13:39:55+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-10-30T13:39:55+00:00urn:sha1:0149b781d438091ce086449101a916e9b4456b4e
In a global initialization, the variable does not pass through
'check_readonly', and therefore a VVARGIND is not normalized to a
VINDEXED.
Fixed initialization of global variables2025-10-29T16:14:48+00:00Roberto Iroberto@inf.puc-rio.br2025-10-29T16:14:48+00:00urn:sha1:d4eff00234dc55dac4cb86b6187f5607c1254f9b
When calling 'luaK_storevar', the 'expdesc' for the variable must be
created before the one for the expression, to satisfy the assumptions
for register allocation. So, in a statement like 'global a = exp', where
'a' is actually '_ENV.a', this variable must be handled before the
initializing expression 'exp'.
