Subject: Re: Float#==. Legacy?


The Float#=~ that Martin suggested is nice, but it still doesn't help 
with one of the problems which (I think) the OP wanted:

x = 1.2
y = 1.2000000000000001
p(x =~ y)       # => true
p([x] =~ [y])   # => false

Array#=~ is not defined now, and Object#=~ always returns false (see 
rb_obj_pattern_match()).

Should Array#=~ attempt to propagate the #=~ call through its members? 
Or is there a good reason why this is left unspecified by ruby.

The same question arises for hashes...

Any ideas?
