 ### BUGS
 -  (read-file "nonexisting/file.csv") shows only "could not open file" - should print filename
+- error: the expression `("/usr/local/var/mlisp")` with message "cannot cast" - should add to what is casting
+- better error reporting..for example ls_dir on non existing dir should prind `pwd` dir
 
 ### TODO
 - documentation
 - add url of source/inspiration to clib/*.cpp
 - add stdtest - to test every functionality
 - add -l option (no linenoise)
-- rename ivaluize
+- add -sb option to remove sheebang line
 - add instrumentation (time, nr of evals, num of atoms, debug info, debug environment etc)
     - add -p (profile/performance option)
 - add debug support function call could keep call stack
-- add better print (coloring output)
 - multiline editting (kilo editor)
 - execute system command should capture stderr
 - add built in for and, or
