Compiler warning for macros that do not return quoted expressions

[João Bernardo]

Hi !

I am quite new to elixir, and I am now learning macros. Today, when writing one of my first macros I was keeping getting an error, after 1h of debugging I realised that the only problem with my code was the lack of the `quote` block.

I was wondering if it is possible and if makes sense to add a compiler warning for macros that do not return quoted expressions ?

I am not sure if every macro should return a quoted expression or not, correct me If I am wrong.

Nonetheless, I believe this would useful thing for beginners and even for experienced developers, because forgetting a simple `quote` is really easy.

Hey João

It's perfectly valid to construct Elixir AST without using `quote`, so adding a warning here would result in the compiler warning when nothing is wrong.

Cheers,

Louis

Thanks !

Btw Louis, can you show me an example where we can construct the AST without a `quote` block ?
