I think that people do not like indentation is because copying and pasting code
from webpages and other sources (maybe from PDF files) might not let the
copying of the code correctly. Therefore it will not be pasted as it should
(and then the code will/might not run as it is supposed to). Files that do not
let the copying of indentations will have that issue. I suppose that then it
would be nice to have an alternative version Nim that does not use indentation
(although that would probably be double the work making such two versions of
Nim). Another option would be to let the users choose to turn indentation on or
not within Nim, but that would make the development of Nim more complicated.
