std::print author here. Indeed, std::print shouldn't be expensive to compile, it's just a thin wrapper around a single type-erased function. The only reason why it is expensive in libstdc++ is that the type-erased function is inlined which goes against the proposed design but unfortunately can't be enforced via the standard wording and remains a Quality of Implementation (QoI) issue.

Fortunately, libstdc++ is fixing this: https://gcc.gnu.org/pipermail/gcc-patches/2026-March/710275..... There is still more work to optimize the includes but it's a good start.
