If I am creating an arithmetic problem solving app, is it a bad idea to use an eval function to have Kotlin evaluate the result of an expression, like

import javax.script.ScriptEngineManager

fun main() {
    val engine = ScriptEngineManager().getEngineByName("kotlin")
    val result = engine.eval("2 + 2 == 4")
...

?
This is to avoid having to implement my own recursive expression parser

Yes, it is a very bad idea. If you do this, your users will be able to execute arbitrary Kotlin code, not just expressions.

If that's what they want, they should just use ki
