Conditional expression must be either alone or inside parenthesis

[Shachar]

As currently implemented, conditional expressions must either come alone (i.e. - not interact with any other operator), or surrounded by parenthesis. So, this is legal:

def chain( number : U64 ) -> U64 {
  if( numer%2 == 0 ) {
    number/2
  } else {
    number*3 + 1
  }
}

And this is also legal:

def chain( number: U64 ) -> U64 {
  ( if(number>12) {number} else {12} ) + 5
}

But this isn't:

def chain( number: U64 ) -> U64 {
  if(number>12) {number} else {12} + 5
}

Currently, this is a limitation of the parser, but we need a debate on whether that's actually a good restriction on conditional expressions.
