New on CTAN: tokmap
Usage: `\tokmap <command> { <tokens> }` applies command over the token list tokens. Space tokens, left and right braces are replaced with the marker tokens `\tokmap@space`, `\tokmap@bgroup`, and `\tokmap@egroup` respectively (who are `\ifx`-equal to themselves exclusively). For convenience, command may contain multiple tokens. It is assumed that `{` and `}` are the only characters with category codes 1 (beginning of group) and 2 (end of group) respectively. Expandable. This package may be used in LaTeX by `\usepackage{tokmap}`, or in plain TeX and other formats by `\input{tokmap}`. See the visualtoks package for an example application (http://mirrors.ctan.org/macros/generic/visualtoks/visualtoks-doc.pdf).
