term_to_atom(?Term, 
?Atom)True if Atom describes a term that unifies with Term. 
When
Atom is instantiated, Atom is parsed and the 
result unified with Term. If Atom has no valid 
syntax, a
syntax_error exception is raised. Otherwise Term 
is “written” on Atom using write_term/2 
with the option
quoted(true). See also format/3, with_output_to/2 
and
term_string/2.
