Perhaps "easily surprised"?  Racket has long had the option to cache
compiled modules and use them if their source has not changed.  

You get this either by running "raco make ..." from the command line,
or, in DrRacket in the 'Choose Language' dialog by selecting the
option to 'Populate "compiled" directories (for faster loading)'.


Not recompiling all the time can be a big time saver.

[racket-users] re-run really fast!

2020-03-04 Thread 'John Clements' via users-redirect
Okay, I’m probably under a rock and just haven’t read my e-mail in a week, but 
… I just noticed that re-running a long TR file of 900 lines took ONE second, 
rather than eleven. It appears to me that either TR or DrRacket or both are now 
cooperating to not re-compile when no edits have been made. Is that a recent 
change, or am I just easily pleased?

[racket-users] Re: Error on F6 after code incorrectly colored as comment, using Large Letters

2020-03-04 Thread Dexter Lagan
  Note that the affected code is correctly displayed after the F6 press 
error. DrRacket seems unaffected beyond the error.
