These are used extensively, so I cant imagine the amount of
interesting side effects from doing this - try doing a select from it,
just for starters

q)tbl:(a:1 2 3;b:5 6 7)

q)(`$("a[s]d";"j(k)l"))xcol tbl
a[s]d j(k)l

1 5
2 6
3 7

.Q.res is a list of reserved words, key`.q will give you q names to avoid
