Yes! This is one of the things I'm definitely looking to add into expr. I discussed this topic with several big companies which have huge expr expressions.

I'm thinking to add support for if expressions and return statement.

First thing is to add alternative for ternary operator cond ? expr1 : expr2 as an if:

if cond { expr1 } else { expr2 }

I'd like to keep syntax for if close to go, but if should still be an expression.

let var = if cond > 0 { 
 "success" 
} else { 
 "also success" 
}

With if as expression, else is required. But with combination with return, else can be omitted:

if cond > 0 {
 return "success"
}
foo + bar

Hey @antonmedv, Thanks for replying!
Good to hear that statements are on the cards.
Are you planning to support something like this as well:

if cond > 0 { 
 varA = 123 
 varB = 987
} else { 
 varB = 456
 varC = 678
}
// then use varA, varB & varC in later code

Basically, we need not return from the if and each if is not bound to return a single value (like you wrote earlier with let var = if ...).
Thanks!
