Aside: you've actually raised a fascinating question. I wonder whether
there
are any programming languages that understand URLs as native data types, so
that *source code* starting with http:// etc is understood in the same way
that source code starting with [ is seen as a list or { as a dict?
Some Smalltalk implementations have something that comes close:
st> 'https://python.org' asUrl retrieveContents
But notice that even here the URL has to be defined as a string. To be
a first class object you would need to do something like this:
url = https://python.org/
The only time you would see that is in config files and languages like
shell where everything is a string so no quotes necessary. They are
implied.
`asUrl` would be a string method returning a URL instance, which also has a
convenient method `retrieveContents` wrapping an http client. Not hard to
do with Python, I think this could be an interesting exercise for a learner.
Sure but the issue is, what to do with it. In any case, it's still just
a wrapper around various string methods. You still need to give the
class a string to create the object.
