Why don't we add a semicolon (;) at the end of the if / else?
In Rust, I noticed that this is all but two kinds of statements. Each expression adding ;
will become an expression. The grammar of rust wants statements to match other statements.
So why don't we add a / " ;
at the end of the expression ? This is also an expression, so why don't we do this:if
else
if true {
println!("true");
} else {
println!("false");
};

The most common answer to the discussion is that it sounds more like what users from other languages expect, and there is no harm in resolving this syntax (since the result is ()
due to semicolons in the branches).
