Variables
=========

   In Lisp, symbols are used to represent variables. Each symbol
contains a "value" slot that is used to contain the value of the symbol
when it used as a variable.

   The normal way to obtain the current value of a variable is simply to
evaluate the symbol of the same name (i.e. write the name of the
variable in your program). The `symbol-value' function can be used to
evaluate variables whose names not known statically.

 - Function: symbol-value variable
     This function returns the value of the symbol VARIABLE in the
     current environment.
