Why can not the derived verb modified by left-each("\:") be parsed

see:

q)0N!parse(“(til 10) ,’ (til 10)”); // each
((';,);(k){$[0>@x;!x;'type]};10);(k){$[0\>@x;!x;'type]};10))
q)0N!parse(“(til 10) ,/: (til 10)”); // right each
((/:;,);(k){$[0>@x;!x;'type]};10);(k){$[0\>@x;!x;'type]};10))
q)0N!parse(“(til 10) ,: (til 10)”); // left each
'“(til 10) ,: (til 10)”

I get a signal raised while parsing the left each expression above, but that expression runs well at the q REPL, why?

Thanks.

Hi,

You need to escape the backslash in the string:

q)0N!parse(“(til 10) ,\: (til 10)”); // left each

((:;,);(k){$[0>@x;!x;'type]};10);(k){$[0>@x;!x;'type]};10))
