Minor documentation inconsistency

[Martin Eden]

Hello authors,

Looks like "global" declaration statement is put incomplete in
EBNF syntax section:

  https://lua.org/manual/5.5/manual.html#9

  stat ::=
    ...
    global attnamelist |
    ...

It should be

  global attnamelist ['=' explist] |

is the same manner as "local attnamelist".


Also I enjoy dedicated and comfortably dense style of this manual.

Many thanks for the feedback.

It seems like "global attnamelist" is also wrong in another way: When you don't supply the ['=' explist], it doesn't accept a spread attribute (first attribute shared between all declared values).

Invalid:

    global <const> varA, varB

Valid:

    global <const> varA, varB = 1,2

Valid:

    global varA<const> varB<const>

Also, it seems like it ignores the const-ness of global variables.

Valid:

    > global test<const> = 45

    > test = 23

What's up with that?
