gives this in JavaScript console and browser hangs:
This program now produces a nice error message in the REPL:
Line 31: Potential infinite recursion detected: stack_frac(0.9953271028037384, { "isPrimary": false, "transMatrix": { "0": 1, "1": 0, "2": 0, ...
However, the display value is so large that scrolling becomes impractical. The display of arguments in error messages needs to be limited in depth.
This is a nasty test for runes. A working version is this: https://share.sourceacademy.nus.edu.sg/dbquf (replace 5,5 by 500,500)
There is no issue for this program regarding the display of values in the REPL. We would need to find a new program where the display of large values occurs in the REPL.
