I added a parameter to conversion tables. This allows expandable
function mapping through braces, and token replacement, again through
braces.
I remember seeing some people asking for key-word definitions. Since
the code is happy with #, I could code something that would convert
\keywords:n {
\cs_new:Npn \mybox:nn #{text}...#{width} {
\hbox to #{width} {#{text}}
}
}
into \cs_new:Npn \mybox:nn #1...#2 { \hbox to #2 {#1} }.
Is that the syntax we want for key-word arguments? Do we want keyword
arguments at all?
> \tl_nest_map_function:nN {ab{cd{e}f}g} \foo:n
Now we have this function and
\tl_replace_tokens:nn {ab{cd#{e}~} \foo: } {
a { AA }
d { \l_foo_tl }
\foo: {~}
# {hash}
}
giving AA b {c \l_foo_tl hash {e} ~} ~
