multiexpand – Variations on the primitive command \expandafter

The pack­age pro­vides two user com­mands; one that per­forms mul­ti­ple ex­pan­sions, and one that does mul­ti­ple \ex­pandafter op­er­a­tions, in a sin­gle macro call. The pack­age re­quires ε-TeX’s \nu­m­expr com­mand.
The au­thor sug­gests that the same ef­fect could be pro­vided by use of the com­mand vari­ant mech­a­nisms of LaTeX 3 (see, for ex­am­ple, the in­ter­face doc­u­men­ta­tion of the ex­per­i­men­tal LaTeX 3 ker­nel).
