Within standard ASDL, the sequences already have an ASDL type. Here's a
snippet that shows both builtin types and derived types:
start = Program(stmt* procs, expr* calls)
stmt = Procedure(identifier name, identifier* params, bool is_test, stmt body)
| Block(int blocknum, stmt* stmts)
| Assign(lvalue target, expr value)
| If(expr cond, stmt action)
| Loop(int times, bool fixed, body stmt)
| AbortLoop(int blocknum)
| QuitBlock(int blocknum)
expr = BinOp(expr value1, str op, expr value2)
| Number(int x)
| Bool(bool x)
| Id(identifier name)
| Call(identifier name, expr* args)
| lvalue
lvalue = Output(bool is_bool)
| Cell(int i)
