feature request - read large files.

I am looking for a way to read files larger than 4095 bytes with a script. Any way to get this?

:set linecount [:len [:readline test.txt]]
:set thisline [:readline test.txt 20]
:set nextline [:readline test.txt]

It would read the number of lines in test.txt into $linecount and the 20th (ok, maybe 21st) line from test.txt into $thisline, and subsequent calls without a ‘line number’ parameter retrieves the next line. So the last line is the same as
:set nextline [:readline test.txt 21]
