I think the issue is whether at this point you get the token '{'
or the literal {.

The KornShell book says explicitly that { is a reserved word after the )
whereas this statement is not in the standard.

The standard does say that it is a token if it is the first
word of a command, so the question is how do you determine when
the first word of a command is.

For example,
        if true ;then ;fi date
date is not considered the first word of the command even though it follows
a complete command.

Note that the standard clearly requires the following to be recognized.
        { if true;then :; fi }
since the } follows the reserved word fi.


As I result, I think that the standard is not correct.
