'colorcolumn' is string containing a comma-separated list of column
numbers. It is not a list in the sense of ":help 41.8".

In the context of the :let command, += means to arithmetically add,
not add to a list or append to a string, so your command is
attempting to increment the vaule of a string. Try this instead:

:let &colorcolumn.=','.getcurpos()[4]
