Synopsis:
$encode(<text>)
$decode(<text>)
Technical:
Given any input, $encode() will return a unique string that can serve as
an lvalue (a variable name that can be ASSIGNed to.) Use $decode() to
retrieve the original text. The $encode() function is case-preserving.
Practical:
The $encode() function is used to convert an arbitrary text string into
a string suitable for use in variable or alias names. This might be
used to set up a hash table keyed with nick!user@host patterns. The
$decode() function does just the opposite, converting a string returned
by $encode() to the original string.
Returns:
encode: encoded string
decode: decoded string
Examples:
$encode(hello there) returns "GIGFGMGMGPCAHEGIGFHCGF"
$decode(GIGFGMGMGPCAHEGIGFHCGF) returns "hello there"
$decode($encode(hello there)) returns "hello there"

Other Notes:
You should not trust $encode() to return any specific string. You may
only trust that it is unique given the input string, and that you may
use the return value as an lvalue. Any other use of $encode() should be
considered an error.
