O.K., any chance to explain the above in Zsh doc?
Just to make sure that I understand:
- "as if in double quotes" means, that I cannot use "..." or '...' quoting
inside of subscript, only back-slash is possible?
- the rule for ``\\'' and ``\$'' still aplies? But ``\"'' is parsed as
*two* characters?
