Just some random thoughts on this:
1) it would be easier to guess what a function does, or how
to use it:
compare this
>> help compress
Compresses a string series and returns it.
Arguments:
data -- Data to compress (any-string)
to this
>> help compress
Compresses a string series and returns it.
Arguments:
data -- Data to compress (any-string)
Returns:
binary! -- Maybe with some more explanation here
which carries more information for you? How do you
use it correctly?
2) If you change the function some time later it is
more likely that you don't introduce changes which
would break existing code.
regards,
Ingo
