AFACS in Boot this is:
interpret_block(code) ==
$newcompErrorCount : local := 0
$inclAssertions : local := []
$ncMsgList : local := []
$erMsgToss : local := false
$lastPos : local := $nopos
$EchoLines : local := false
st := MAKE_-STRING_-INPUT_-STREAM(code)
intloopInclude0(st, 'webspad, 0)
Both Lisp version and the above behave rather badly when called
from command line (the same is true for parseAndEvalStr).
Namely, after calling it interpreter is apparently waiting
for more input from the string, but none is coming. So
command line is effectively blocked. Probably does not
matter for server style use, but definitely it is not "universal"
function.
