\DOC preterm_of_term
\TYPE {preterm_of_term : term -> preterm}
\SYNOPSIS
Converts a term into a preterm.
\DESCRIBE
HOL Light uses ``pretypes'' and ``preterms'' as intermediate structures for
parsing and typechecking, which are later converted to types and terms. A call
{preterm_of_term `tm`} converts in the other direction, from a normal HOL term
back to a preterm.
\FAILURE
Never fails.
\USES
User manipulation of preterms is not usually necessary, unless you seek to
radically change aspects of parsing and typechecking.
\SEEALSO
pretype_of_type, term_of_preterm.
