Pretty much for that reason. #species allows
some collection methods to return a more general type if
the specific type might not yield expected or pleasant results. E.g.
#f00,var1,' ',var2,' = ',var3
would produce lots of intermediate symbols with the associated
overhead when a string result is more likely the desired result.
BTW, Andreas simply moved the existing Symbol>>species into
ByteSymbol and WideSymbol when they entered Squeak. The original use
is much older.
Cheers,

Why would this be? I mean, it has Andreas' initials on it so I presume
there's good reason.
It means that #foo, '1' returns 'foo1', not #foo1.
(This is why the ClassFactoryForTestCase-using tests are all failing.
The fix for the tests is in SUnit-fbs.94.)
