Hi,

I know Symbol is subclass of String.        

Any string object can become symbol object by sending 'asSymbol' message..

I think  symbol must has its meaning in comon use, so the symbol should be composed of alphabet or number ��without space��.

BUT There are not compliant below

1.    '     ' asSymbol     >>>>    no meaning

2.  '$%%&' asSymbol     >>>>    no meaning

3.  'sign' asSymbol = 'sign ' asSymbol   >>>  false because of space.

3. '  one two  three ' asSymbol              >>>    I think It should become three symbols = #one, #two, #three

Mybe my understanding is wrong.
