sets.
For pair sets, expressions like <cf/(123,*)/ can be used to denote ranges (in
that case <cf/(123,0)..(123,65535)/). You can also use <cf/(123,5..100)/ for range
<cf/(123,5)..(123,100)/. You can also use <cf/(*,123)/ which is translated as
<cf/(0,123) , (1,123) , (2,123) , ... , (65535, 123)/
<cf/(123,5)..(123,100)/. You can also use <cf/*/ and <cf/a..b/ expressions
in the first part of a pair, note that such expressions are translated to a set
of intervals, which may be memory intensive. E.g. <cf/(*,4..20)/ is translated to
<cf/(0,4..20), (1,4..20), (2,4..20), ... (65535, 4..20)/.
You can also use expressions for both, pair sets and int sets. However it must
be possible to evaluate these expressions before daemon boots. So you can use
only constants inside them. E.g.

Sets of prefixes are special: their literals does not allow ranges, but allows
