In Wren identifiers consist of upper and lower case letters, digits or underscores and must begin with either a letter or an underscore. Only ASCII letters or digits can be used, though Wren supports Unicode for other purposes.
Identifiers which begin with underscores can only be used as instance field names (one underscore) or static field names (two or more underscores).
<lang ecmascript>for (i in 97..122) System.write(String.fromByte(i))
for (i in 65..90) System.write(String.fromByte(i))
System.print("_")</lang>
