procedure
(paren-x64-v1? a) → boolean?
a : any/c
Decides whether a is a valid program in the paren-x64-v1 grammar, represented as a quoted datum. The first non-terminal in the grammar defines valid programs.
procedure
(interp-paren-x64-v1 a) → any/c
a : paren-x64-v1?
Evaluates a paren-x64-v1 program to a value.
