My code: https://gist.github.com/MikailBag/5803041040c052deda1d06893eae67e1
(Please note that is requires stdexec, which is AFAIK reference implementation of the C++26 `std::execution`)
When running `build.sh`, I get following error:
```
/tmp/build/vcpkg_installed/x64-linux-clang/include/exec/../stdexec/__detail/__transform_sender.hpp:103:9: error: definition with same mangled name '_ZNK7stdexec8__domain18__transform_senderclIS1_NS_14default_domainENS_7__sexprIXtlNS_12_GLOBAL__N_1UlvE8_EEENS5_6__anonEEEJNS_5__env9empty_envEEEEDcT0_OT1_DpRKT2_' as another definition

```
I'm not an experienced modules user, so I can easily be wrong, but I don't see anything wrong in terms of linkage/ODR/etc. And based on #53232 it seems, that this error is in fact internal to compiler.
Here is compiler version (it was installed from the LLVM APT repository):
```
$ clang++-19 --version
