Another reason is that we allow the programmer to refer to systems with 
symbols as well as strings, and symbols are not -- without a substantial 
nuisance -- case-sensitive.

I'm afraid you are better off with "solve-solvable2".  And avoid 
"solve_solvable" because underscores are not legal characters in logical
