Re: Performance of list / array / dict compared

Python has the equivalent of Lists, Arrays, and Dictionaries -- which
did you use?

in Python the plain list is used (well, these details could be quickly
seen by the link to sources above) - as I mentioned in TCL I decided to
try other structures only because I thought list implementation could be
not very effective internally, e.g. due to historical reasons...

For calculation, C or Golang would likely be best.

Not necessarily, any language compiled to native codes will do
similarly. Moreover, there is optimized version of Python - and there is
JIT-version for Lua, while Java uses JIT anyway, so they results are
very close:
Java: 1.60
Pypy3: 7.31
LuaJit: 2.18
Perhaps someone may one day try to use JIT in TCL also (perhaps even
borrowing it from Lua may work)
