Deeply nested result rendering¶

Rendering a deeply nested result must not overflow the stack. The interpreter runs on a large-stack worker thread so nesting depths that wolframscript renders (here a 3000-deep list) are handled rather than crashing.

$ wo 'StringLength[ToString[Nest[List, {1}, 3000]]]'
6003

A deep symbolic tower renders too:

$ wo 'StringLength[ToString[Nest[f, x, 3000]]]'
