Subject: GEMs pollution or not?

Hello,

While developing a module that implements a « CRON calendar », I also
created a few « utility modules ».

When you develop such module, you write functions that are not coupled
to your module.

For example : a function that returns the list of "days of the month"
that correspond to a list of "days of week" (within a given month of a
given year). This function may be used for other purposes than a « CRON
calendar ». Therefore, I put this function in a « date utility module ».


1 -- I can include the « date utility module » within the « CRON
calendar GEM ».

or

2 -- I can create a « date utility GEM ». The « CRON calendar GEM » will
have a dependance with the « date utility GEM ».


The second solution seems better. But : the « date utility GEM » may
change in the future, since I'll be adding more and more functions into
it. In other words : this GEM is a kind of heap of functions with no
other thing in common than date and time finality.

If everybody creates a GEM for this kind of thing, this may pollute the
GEM repository.

What's your advice?

Thanks,

Denis
