Hello,
when '(' appears in the shell input, how does the section 2.3 Token
Recognition, of the shell standard, recognize it?
'(' can be start of a subshell, or function, or optional start of a `case`
pattern, but nowhere do I see any indication that this is an operator, or
reserved word. Hence it seems to me, that when following section 2.3, no
earlier rule than 9 would apply, so either by rule 9 or 11, '(' is part of a
word.
But that is not how dash behaves:
$ f(
dash: Syntax error: newline unexpected (expecting ")")
$
instead of trying to execute 'f('
So how is '(' recognized?
Thank you,
Mark
