Incorrect Parse in global statement

[Xpectuer]

When global statement is parsed, there is a incorrect behavior.
Here is the example
source:

global a = 1, b

The statement above is parsed into:

(global 
(assign a (tuple 1 b)))

whereas the expected one is:

(global 
(assign a  1) b)

Hope for a fix.

What makes you think that this is the expected behaviour? We're matching Meta.parse here:

julia> CSTParser.parse("global a=2, b")
  1:13  global
  1:6      1:1   OP: =
  1:1     a
  2:5     tuple
  2:2      INTEGER: 2
  3:3      b

julia> CSTParser.to_codeobject(CSTParser.parse("global a=2, b"))
:(global a = (2, b))

julia> Meta.parse("global a=2, b")
:(global a = (2, b))

julia> global a = (2,b)
ERROR: UndefVarError: b not defined

julia> b = 2

julia> global a = (2,b)
(2, 2)

julia> a
