The main problem with library solutions is the fact that
corresponding language services are not available for them (think
of code completion). Even if a language service will make the
effort to interpret a library construct like SafeAccess!stuff and
provide code completion, it will not work for other names - maybe
I'd like to use Elvis!stuff. On the contrary, if it's built in
the language and the meaning of stuff? is guaranteed to be the
same across compilers, the language services can safely assume it
and provide all associated goodies.
The same problem is encountered with property bloat code, mixin
constructs are not the best friends of language services.
