Description

This is related to issue #20: execution order control. Right now, <test> in (elif <test> <body>) can only be a single JS expression, the compiler throws an error if it compiles to multiple lines. We should check if those multiple lines can be included as comma-separated expressions, and when not, include them as self-executing lambdas or reference calls.

Research direction

Start with the compiler path for (elif <test> <body>) and review issue #20 for the execution-order context. Determine how multi-line JavaScript expressions should be represented in elif tests, including when comma-separated expressions are insufficient; done means such tests compile without the current error and preserve the intended evaluation order.
