 A problem:

 365 maps were produced using an r.sun(script) with a common prefix. It is
 required to extract average values per month [i.e. (1+2+...+31)/31,
 (32+33+...+ 59)/28, etc.]. For this task r.series can be used and,
 naturally, typing 31+28+... map names to feed the "input=" can/should be
 avoided.

 Figuring out a wildcard(s) pattern or regular expression to pick e.g. only
 maps 001 to 031 out of 365 (all of them with the same prefix of course) is
 not easy (I think). The usual way of using "[0-something]" per character
 trick, will return also maps >031. My understanding is that g.mlist is
 also not "smart" enough to solve this quickly.


 A wish:

 How about adding such a functionality? Given there are many maps with a
 common prefix, the user can set a $BEGIN and an $END number and g.mlist
 would return those (counting from $BEGIN, adding all existing numbered
 maps up to $END) with the separator that the user has set.
