You can call it a statement all you want but if it produces a value, its an expression. And it does produce produce a value.

Here's the description of method return from "the ruby programming language" book:

> If a method terminates normally, then
the value of the method invocation expression is the value of the last expression evaluated
within the method body.

the last expression in my example is `1 if false` with no parens



----------------------------------------
Feature #18040: Why should `foo(1 if true)` be an error?
https://bugs.ruby-lang.org/issues/18040#change-92957

* Author: bughit (bug hit)
* Status: Open
* Priority: Normal
----------------------------------------
There's no ambiguity here that should require another set of parens `foo((1 if true))`
