Since I haven't posted to this group in the past 5 years or so, let me 
start by saying how much I enjoy using Ruby!  My comments below reflect 
my desire to see a couple of small issues improved in this extraordinary 
language!


The first is a requested feature (which works in 1.8.7 but not in 
1.9.2p136), while the second appears to me to be a bug that exists in 
both 1.8.7 and 1.9.2:

1. Range.step says (per PickAxe 3) that it works with range elements 
that support .succ, or with numbers.  It would be nice to have it work 
with elements that support .succ, /or with elements that support adding 
a number to them/.  This would allow stepping through time ranges, for 
example.

2. Range.step where the end is specified to be excluded ( '...') on 
floats seems to exclude the last value that should be included.  For 
example:
     ( 1.0 ... 5.01).step( 2) {|x| puts x}
     outputs 1.0 and 3.0 but not 5.0.
     Interestingly, ( 1.0 ... 5.01).cover?( 5.0) returns true, as it should!
