Uwe Lück submitted the 


package to CTAN.

Summary description: Expandable iteration on comma-separated and filename lists
License type: lppl

Announcement text:

`commado.sty' provides 


to apply an existing one-parameter macro <cmd> to each item 
in a list <list> in which items are separated by commas. 

`filesdo.sty' provides 


to run <cmd>{<base>.<ext>} for some (at most) one-parameter 
macro <cmd>, each base filename <base> in the comma-separated 
list <bases> and each extension in the comma-separated list 

As opposed to LaTeX’s internal \@for, no assignments are 
involved (unless <cmd> uses assignments, "expandability" in 
"TeX’s gullet").

Both packages are "generic," i.e., should work with Plain 
TeX, LaTeX or even other formats, relying on the `plainpkg' 
package for some minimal LaTeX-like behaviour.

RELATED PACKAGES: `loops' and others mentioned in the 
    `dowith' package documentation.

KEYWORDS: macro programming, programming structures, loops, 

REQUIRED PACKAGES: `plainpkg', `stacklet'
