Description

Related to #12402, I found other kind inconsistencies.

simple assignment and op assign of command cause syntax error,
while simple assignments don't.

$ ruby -ce 'a = b = raise "x"'
Syntax OK

$ ruby -ce 'a = b += raise "x"'
-e:1: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '('
a = b += raise "x"
                ^

$ ruby -ce 'a += b = raise "x"'
-e:1: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '('
a += b = raise "x"
                ^

$ ruby -ce 'a += b += raise "x"'
-e:1: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '('
a += b += raise "x"
                 ^
