hello.when i use marco__func__ with AY_OBFUSCATE(),the complier throw this error:

error: template argument 1 is invalid
206 |         []() -> ay::obfuscated_data<sizeof(data)/sizeof(data[0]), key>& { \
    |                                                                      ^

how can i use __func__ with AY_OBFUSCATE? thanks :）

I don't think this is an issue you can work around in an efficient way.

In contrast to macros like __DATE__, __TIME__, or __LINE__, __func__ is actually an implicitly created constant not known to the preprocessor. This would have worked with __FUNCTION__ in old versions of GCC (I think), but since by now that macro also just points at __func__, I don't think there's any simple way around this other than inserting function names by hand (or doing some macro magic).

And even if you could work around this, you'd probably be lost due to AY_OBFUSCATE() inserting a lambda, which inside would feature a different value for __func__.
