#5923: Handling of magma and pari input in ModularForms
---------------------------+------------------------------------------------
 Reporter:  ljpk           |       Owner:  craigcitro
     Type:  defect         |      Status:  new       
 Priority:  minor          |   Milestone:  sage-3.4.2
Component:  modular forms  |    Keywords:            
---------------------------+------------------------------------------------
 The ModularForms command has some slightly counter-intuitive behaviour on
 some types of input:

 {{{sage: ModularForms(gp(1),12)
 ---------------------------------------------------------------------------
 TypeError

 [much snipped error message]

 TypeError: Error executing code in GP/PARI:
 CODE:
         sage[4]=level(sage[3]);
 GP/PARI ERROR:
   ***   expected character: ',' instead of: sage[4]=level(sage[3]);
                                                               ^-----
 }}}

 I realize that this is because the first element is supposed to be a
 group, although a (Sage) integer is allowed.

 Would there be any support for having an if statement in the function to
 catch magma or pari elements and transform them into their Sage
 equivalents?
