\begin{funcdesc}{compile}{string\, filename\, kind}

Compile the \var{string} into a code object. Code objects can be

\code{eval()}. The \var{filename} argument should

give the file from which the code was read; pass e.g. \code{'<string>'}

if it wasn't read from a file. The \var{kind} argument specifies

object and a string. The string must be the name

of one of the object's attributes. The function deletes

the named attribute, provided the object allows it. For example,

\code{del \var{x}.\var{foobar}}.
