is following possible in kotlin? if not, what will be the kotlin way to do it

while (isalnum(LastChar = getchar())) {
    IdentifierStr += LastChar;
}

taken from c++.

probably something similar to this? It's not equivalent but I can't see the context..

val identifierStr = generateSequence { getChar() }
.takeWhile { isalnum(it) }
.joinToString(separator = "")

[E.Kisaragi]

val list = getChars()
val identifier = list.takeWhile { it.isAlphabet() || it.isDigit() }.joinToString()

like that? idk

thanks! first one sounds good.
