BUGS

• (read-file "nonexisting/file.csv") shows only "could not open file" - should print filename
• better error reporting..for example ls_dir on non existing dir should prind pwd dir

TODO

• add debug support, at least call stack
• multiline editing (kilo editor)
• execute system command should capture stderr
• add some mem stats to benchmark
• create pastebin like web using ml

Code

• documentation
• rename constants in ml_profiler.h
• replace to_string macro in ml.cpp
• add url of source/inspiration to clib/*.cpp
• add instrumentation (time, nr of evals, num of atoms, debug info, debug environment etc)

Language

• support for "t" symbol as a true
• support for exceptions
• string functions
  • compare - needed for sorting, cmp ignore case
  • regexp functions
• date support
  • decode-universal-time
• env functions
  • get-env, set-env; set-env cannot be implemented in stdlib.lsp, because popen is in fact subshell
• add include-stdlib function for other libs in stdlib dir (during startup stdlib.lsp is loaded only)
• syntax highlighting do VS Code

Performance

• define is one of most frequent callee, when in scope with very few vars, lookup sequentially
• first, second are often called -> implement in c++
• push_back - repeatedly without reserving size
• range - with for(int i...) and reserving result size can be 3times faster on (range 1 10000)
• mini_sprintf - unnecesary copying between vector and list
• (do, scope ..) repeatedly assign to acc
