I think that any sequence of bytes, including the empty sequence
should be mappable to a symbol. To me, the the Symbol class is a
guaranteed one-to-one mapping from a string instance to object.
The symbol literal notation and String#to_sym make the mapping easily
accessible. Making an exception for the empty string seems to be
unnecessary.
Regarding Symbol#empty?, let me throw out a related idea, the idea of
a 'zero' object(s) of a class. Of course the numeric classes already
supports this:
0.zero? #true
1.zero? #false
(0.0).zero? #true
3.nonzero? #true
I think incorporating the more expansive idea of 'zero' as found in
abstract algebra and category theory might be useful in Ruby. There
are zeroish elements in other classes:
"" from String
[] from Array
{} from Hash
nil from NilClass
One way to view an object as the 'zero object' is the way it behaves
with respect to addition:
3 + 0 # 3
0 + 3 # 3
"" + str # str2 where str2 == str
str + "" # str3 where str3 == str
[] + ary # ary2 where ary2 == ary
ary + [] # ary3 where ary3 == ary
It would be nice if this worked for Hash also:
def m(options={})
options = Defaults + options
#...
end
Rail uses the predicate blank? to get at this idea of 'zero-ness'.
Why not just use zero?
This pattern is also a nice way to incorporate the null object
pattern into user defined classes. The null object returns true for
zero? while any other objects return false. This allows test for
zero? to automatically be true for nil also:
def m(arg)
if arg.zero?
#
end
end
So back to Symbols. Symbols don't really support any operations but
it seems like the idea of identifying the symbol with an empty name
as the 'zero' symbol has a nice symmetry to it:
Zero Object(s)
NilClass nil
Symbol :""
String ""
FalseClass false
TrueClass (no zero object)
Array []
So I guess I'm saying that Symbol#empty? might not make sense while
Symbol#zero? might be a nice way identify the 'zeroish' symbol.
