How to use multiple variables in let in Kotlin?

Hi everyone! I recently started learning Kotlin and ran into a problem when working with the `let` function. I know that `let` allows you to execute code only if the object is not null, and it's very convenient for safe work with nullable types.\n\nBut what should I do if I have several nullable variables and I want to execute a block of code only when all of them are not null? For example, I have this code:\n\n```kotlin\nval name: String? = getUserName()\nval age: Int? = getUserAge()\nval email: String? = getUserEmail()\n\n// How to combine checks for all three variables?\n// I tried to do it like this, but it results in nesting:\nname?.let { n ->\n age?.let { a ->\n email?.let { e ->\n println("Name: $n, Age: $a, Email: $e")\n }\n }\n}\n```\n\nThis works, but it looks terrible — it's too
