Bruno Le Floch submitted the
multiexpand
package to CTAN.
Summary description: Variations on the expandafter primitive License type: lppl
Announcement text: ----------------------------------------------------------------------
Macros meant to avoid using too many expandafter. Should hopefully be compatible with plain, LaTeX and ConTeXt, but requires eTeX's umexpr.
This was written before I had understood LaTeX3's variant mechanism, and I advise people who fight with expansion to use LaTeX3 rather than multiexpand.
