expr-lang playground shows incorrect "Explain" for expressions

[rchougule]

expr-lang supports short-circuiting of expressions. Though, the playground seems to be depicting otherwise.

For e.g.,

1. true || functionCall()
2. functionCall() || true

In both these cases, the functionCall() is not invoked actually when tested. But when looked at playground, it seems to Explain in a way that it does.

• Incorrect Explain

• Correct Bytecode though

Yes, this is "by design". In the explain more, Expr will evaluate both branches. I guess this is not intuitive behavior. I will turn on short-circuting by default in explain.

Thanks a lot!

Hi @antonmedv, just reaching out to check on when are we planning to enable this.
Thanks!

Hey, yes. This already implemented in Expr Pro. I have plans to deploy this to Expr Playground this week.
