in j803+ gethash is dyadic
'MD5'&gethash 'asdf'
A neat trick for simulating "break." tacitly with power is to modify the shape
of input on success/break condition. I.@(boolexp) returns 0 if true, or null
if not, and appending the result of I@:f, to next y can signal break with a
cheap test.
<:@{: 'bgvyzdsv' (>:@] ,~ I.@:('00000' -: 5 {. 'MD5'&gethash)@,&":)^:(0 <
{.@])^:(_) 1
