Re: Prepend/append to the members of a list

Even if history substitution did understand beginning-of-word, that
still wouldn't work.  You'd at the least need :gs and some character
other than slash as the separator.

Usually in this situation I would do something like

% (cd dir; !ls )

Nikolai's suggestion can be tweaked to not require rcexpandparam:

% a=( !ls:* ); ls dir/$^a

Or this:

% ls dir/${^$(echo !{ls:*:q})}

} Or another example:
} % cp dir/*.[1-9](:t:s+^+/usr/share/man/man?/+:s/$/.gz/) .

There you're in a bit of a pickle because you're using history modifiers
on a glob pattern, which is even more limited.  I believe the closest
you'd get without pain [#] is:

% cp /usr/share/man/man?/${^$(echo dir/*.[1-9](:t)}.gz .

which isn't that much uglier than what you constructed.

Of course, if you do this specific thing often you can do

% function mangz { reply=(/usr/share/man/man?/$REPLY:t.gz) }
% cp dir/*.[1-9](+mangz) .

[#] Pain is safely quoting special characters in the file name:

% cp /usr/share/man/man?/${^$(echo dir/*.[1-9](:te.'reply=${(q)REPLY}'.))}.gz .
