Just To You, :-)

Symbol , a sign with some meaning in nature language.

eg, #% = percent, #$ = dollar.

but

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

symbol as a message should have his meaning. defined in its method.

a message should let programmer know what to do.

I come from China , My English is poor.

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

I don't know what you mean by "no meaning', they're symbols.
Try this in a Playground, it works in Pharo 5"

| oc sym filtered|
oc := ' one two three $%%&' splitOn: ' '.
sym := OrderedCollection new.
oc do: [:each | sym add: each asSymbol].
filtered := OrderedCollection new.
filtered := sym select: [ :each | each ~= #'' ].
Transcript show: sym printString; cr.
Transcript show: filtered printString; cr.

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��.

Mybe my understanding is wrong.
