GarboMuffin 20f25f252c interpreter: Do not re-evaluate procedure arguments after stop this script or return (#202) 
"stop this script" and "return" would previously cause all the procedure
arguments to be re-evaluated and then discarded. In vanilla Scratch the
worst case is a performance penalty, but with our custom reporters it
can cause infinite loops.

Thomas Weber ec20b19f13 Add a few comments 2021-05-24 16:59:51 -05:00
Thomas Weber 5659a42b30 Make startHats not O(n^2) 
For hats with restartExistingThreads=true, a map of target ID +
thread top block ID is maintained in addition to the thread list.
Then, startHats can do a simple lookup instead of iterating over
the entire thread list. Can improve performance in certain
projects that use way too many broadcasts and clones. These
lookups are probably O(1)-ish instead of O(n).

This is not possible for hats with restartExistingThreads=false
due to the extra .status === Thread.STATUS_DONE check.
