@nicolasstucki does the macro section look good?

@nicolasstucki @alemannosara do you think we can mention the f-interpolator? Do we have the docs for it somewhere?

Macro section looks good

[nicolasstucki]

We can mention f interpolators. We do not have docs, the change is that now all the compile-time checks that scala2 did are implemented as a macro in dotty.

[anatoliykmetyuk]

Can you please elaborate on what I should write about it?

[nicolasstucki]

I think it is enough to state the we fully implemented the f interpolator as a macro. We can also add this link https://docs.scala-lang.org/overviews/core/string-interpolation.html#the-f-interpolator
