You want 0!:111 or some variation (your options are at [1]):
EXPR=:'1+1'
0!:111 EXPR
1+1
2

Your EXPR can be multi-lined: an entire J script (including explicit
definitions), in fact. And yet it doesn't introduce a new name context
(i.e. it can still access your local names, if you're calling it from an
explicit definition).
In fact, 0!: is exactly how "load" and friends work. Try for example
loadd 'script' (or 1 load 'script') or press CTRL+SHIFT+W (as opposed to
just CTRL+W) in an IJS window.

When do we ever say that here?
