Crosscut

Postfix syntax has advantages over prefix syntax, but you can offset those. And there is at least one genuine advantage that prefix syntax has over postfix (besides familiarity; which, to me, doesn't count). Because this is shit:

condition
then_case
else_case
    if

This is a fictional postfix syntax for an if expression. And I don't like it, because I have to read three distinct pieces of code (condition, "then" case, "else" case) before I'm told the context (if) that could help me understand this.

We can make that a bit better by being more explicit:

{
    condition: ...
    then: ...
    else: ...
}
    if

At least this way, you see a record type that starts with a condition field, and can pretty much assume what this is going to be. But it's not the same as knowing the context of what's happening from the start. Like you would, if this was using prefix syntax, and if was the first thing you saw.
