Editing S-expression (section)

==Datatypes and syntax==
There are many variants of the S-expression format, supporting a variety of different syntaxes for different datatypes. The most widely supported are:
* ''Lists and pairs'': <code>(1 () (2 . 3) (4))</code>
* ''Symbols'': <code>with-hyphen</code> <code>?@!$</code> <code>|a symbol with spaces|</code>
* ''Strings'': <code>"Hello, world!"</code>
* ''Integers'': <code>-9876543210</code>
* ''Floating-point numbers'': <code>-0.0</code> <code>6.28318</code> <code>6.022e23</code>

The character <code>#</code> is often used to prefix extensions to the syntax, e.g. <code>#x10</code> for hexadecimal integers, or <code>#\C</code> for characters.
