print_text_stream stream ==
if stream then
while (str := read_line stream) repeat
WRITE_-LINE str
print_text_file filename ==
handle_input_file(filename, function print_text_stream, [])

Shall we use "WRITE_-LINE" or define "|write_line|" or use
"SAY" or "PRINC"?
And is there a better place to put it other than i-syscmd.boot?

"with-open-file" is hard to express in Boot, right?
To use "open" directly, there's risk when IO error happens,
file handler are not properly "close".
We have 'handle_input_file' which is a wrapper around
'with-open-file'. Since there is no macros in Boot,
'handle_input_file' takes a function as an argument.
