// Essentially normal Python has 1 type: Python objects
|
|
|
|
// Viper has more than 1 type, and is just a more complicated (a superset of) Python.
|
|
|
|
// If you declare everything in Viper as a Python object (ie omit type decls) then
|
|
|
|
// it should in principle be exactly the same as Python native.
|
|
|
|
// Having types means having more opcodes, like binary_op_nat_nat, binary_op_nat_obj etc.
|
|
|
|
// In practice we won't have a VM but rather do this in asm which is actually very minimal.
|
|
|
|
|
|
|
|
// Because it breaks strict Python equivalence it should be a completely separate
|
|
|
|
// decorator. It breaks equivalence because overflow on integers wraps around.
|
|
|
|
// It shouldn't break equivalence if you don't use the new types, but since the
|
|
|
|
// type decls might be used in normal Python for other reasons, it's probably safest,
|
|
|
|
// cleanest and clearest to make it a separate decorator.
|
|
|
|
|
|
|
|
// Actually, it does break equivalence because integers default to native integers,
|
|
|
|
// not Python objects.
|
|
|
|
|
|
|
|
// for x in l[0:8]: can be compiled into a native loop if l has pointer type
