I just finished writing the first draft of my first propos= al ever.
And before submitting it, I'd like to discuss the matter at= hand, and the proposal at this forum.

The proposal is about adding = traits, to determine a lambdas return and argument type(s) at compile time,= to the standard library.

Have a look,
I'm open to all kinds of criticism and feedback :)<= br>
