Scope functions apply/with/run/also/let: Where do the names come from?

Question

There are quite a few blog posts (like this) on usages of the standard library functions apply/with/run/also/let

Answer 1

Adding to the @kirillRakhman answer:

A major part in the naming process was (still is) fluent reading experience in major use cases.

with:

with(database) {
    open()
    send()
    close()
}

apply:

val v = View().apply {
    width = 3.0
    height = 4.0
    register(this)
}

also:

db.users()
    .filter { it.age > 18 }
    .map { account }
    .also { log(it) }

IMHO it doesn't really work with let well. After all, it was taken from "those scary FP languages". But I often think of it as a sort of Let's do this! construct. Like below you could read the code as let's print it!:

account.map { it.owner }.sumBy {age}.let { print(it) }
