The simplest kind of expression is a literal MOO value, just as described in the section on values at the beginning of this document. For example, the following are all expressions:
17
#893
"This is a character string."
E_TYPE
{"This", "is", "a", "list", "of", "words"}
In the case of lists, like the last example above, note that the list expression contains other expressions, several character strings in this case. In general, those expressions can be of any kind at all, not necessarily literal values. For example,
{3 + 4, 3 - 4, 3 * 4}
is an expression whose value is the list {7, -1, 12}.
