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 eTeX’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).
