Lists in inline code don't get a space after commas. (That keeps the
code more compact and avoids line breaks in the middle of the code.)

- Small improvements in the manual
Functions with vararg tables don't need hidden args.2025-11-28T18:12:51+00:00Roberto Iroberto@inf.puc-rio.br2025-11-28T18:12:51+00:00urn:sha1:a07f6a824197d7dc01c321599d3bc71936a2590e
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.

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.
Standard allocator function added to the API2025-10-17T16:53:35+00:00Roberto Iroberto@inf.puc-rio.br2025-10-17T16:53:35+00:00urn:sha1:b352217b8498a5ed8f6c954b3da365fcbb89751f
That makes easier to redefine luaL_newstate.
Optimization for vararg tables2025-09-24T21:33:08+00:00Roberto Iroberto@inf.puc-rio.br2025-09-24T21:33:08+00:00urn:sha1:25c54fe60e22d05cdfaa48c64372d354efa59547
A vararg table can be virtual. If the vararg table is used only as
a base in indexing expressions, the code does not need to create an
actual table for it. Instead, it compiles the indexing expressions
into direct accesses to the internal vararg data.
