Is "milliseconds" part of the grammar/TimeUnit class/enum? about wyldcard HOT 1 CLOSED

Surprised that leaving out a tree visitor method would produce the behavior you describe, especially with an empty script (but can't say I've tried). Every character you type into the script window causes the parser to run in the background so as to provide the live syntax checking feature. The script is considered malformed if the parser throws an exception (which would likely occur if you forget to override a tree visitor method).

TimeUnit is confusing because there are actually two different TimeUnit enumerations being used: the one of my invention (com.defano.hypertalk.ast.model.TimeUnit), and Java's built-in one (java.util.concurrent.TimeUnit). I think I created mine to introduce HC's concept of ticks.

The unquoted string literals in WyldCard are implemented in the public Value getVariable(String symbol) method of ExecutionContext. In your example, the done in put done is parsed as a symbol (variable). When no value has been put into that variable, the symbol is resolved to its own name.

Trying to support multi-token unquoted literals is certainly possible, but would require a huge amount of parser gymnastics and a context sensitive evaluation of the argument passed to put. (And probably a bunch of weird cases where the expected behavior is not obvious to script author.)
