As a result, internal names (e.g., method names) are usually symbols.
Strings are normally used for string manipulation, symbols for
unambiguous (but humanly readable!) internal reference (vulgo 'naming').

Hello everyone,
i'm learning Pharo and i'm having difficulties to understand the symbols,
what are they? How are they different of the ByteString ? Why are they
usefull ?
Why should I put #string where I can put 'string' ?
Thanks in advance for your answer.
