The main thing is to keep the S expressions' data/code duality. Python
doesn't have it. Here's a Python program:
for i in range(10):
print(i)
Here's the abstract syntax tree of the same program (generated by
ast.dump):
Module(
body=[
For(target=Name(
id='i',
ctx=Store()),
iter=Call(
func=Name(
id='range',
ctx=Load()),
args=[Num(n=10)],
keywords=[],
starargs=None,
kwargs=None),
body=[Expr(value=Call(
func=Name(
id='print',
ctx=Load()),
args=[
Name(id='i',
ctx=Load())],
keywords=[],
starargs=None,
kwargs=None))],
orelse=[])])
In Scheme, code is its own abstract syntax tree.
