Well, you'd certainly have something here if your shell did that. It
wouldn't be a POSIX shell, though.
it was my mind shell
does it mean it wont ever get to be the regex /<<([^ \t\f\v\r\n;]+)
that is, after << is parsed a read word till next space,
That's just not how it works, and never has. There's no exception for the
word that is the here-doc delimiter. It's a shell word like any other; the
difference is in the expansions it undergoes.
no shell expansion
logic of separated functional structures in the topic of flat data is
overruling, you are overseeing
for me <<$( e o f )
blabla
$( e o f )
is pure early bug
It's simply not the `flat data' you think it is or should be.
(And that construct is certainly not something anyone should use, `early
bug' or not.)
