Working on a compiler plugin that used andandSymbol to generate code like expr1 && expr2. This works on JVM and JS targets but fails with a TODO() in the LLVM lowering. Is this expected to work and I should file a bug? Or since we're spinning IR should we be expected to use lower-level constructs like explicit branches? I ended up using `ifThenElse`/`irFalse` as it was the most terse IR structure I could find to model this code.

I am pretty sure Compose generates && somewhere
Probably worth comparing your output with compiler generated IR

It emits a when. I copied it initially.

It produces suboptimal JS, from what I remember. Didn't check Java bytecode or LLVM IR.
