statement with no effect warning

[leonardo-m]

This is an enhancement request. This little program currently compiles with no warnings:

fn main() {
    "sss";
    10;
    10 == 10;
}

Clippy gives three "statement with no effect" warnings. I think such warning should be raised by the rustc compiler too.

Thanks! This is actually a duplicate of #32108. Either way, I think this would need an RFC to be implemented due to the nature of lints, but I'm uncertain.

Yes, new lints require RFCs.
