Maybe move ssl imports into a TYPE_CHECKING block?

I made a package to patch httpx for using in pyodide, and you can try a live demo here.

The problem is, code inside httpx have imports to ssl, so I have to install ssl (in pyodide runtime, these modules not bundled by default). But ssl is heavy and I only see type imports inside httpx with ssl, so I wonder can try this:

if TYPE_CHECKING:
    import ssl

# original: def load_ssl_context_no_verify(self) -> ssl.SSLContext:
def load_ssl_context_no_verify(self) -> "ssl.SSLContext":

Or

from __future__ import annotations

if TYPE_CHECKING:
    import ssl

def load_ssl_context_no_verify(self) -> ssl.SSLContext:

Current httpx already does the TYPE_CHECKING split in httpx/_config.py. The module-level import ssl is behind TYPE_CHECKING, and create_ssl_context() does import ssl only when you actually build a context.

So HTTPS still needs ssl at runtime. Importing httpx for a type annotation should not.

If Pyodide still pulls ssl on import httpx, check httpcore (and any httpx[http2] extra). Those can import OpenSSL bits at import time even when httpx itself is lazy.

You cannot drop the runtime import entirely. ssl.SSLContext is used for real connections, not just types.
