Thanks for the suggestio

If you can afford a dependency on rlang, `rlang::zap_srcref()` deals
with this. It's recursive over expression vectors, calls (including
calls to `function` and their hidden srcref arg), and function
objects. It's implemented in C for efficiency as we found it to be a
bottleneck in some application
