The variable .sh.value is a string, not a compound variable, If you do
.sh.value=$'(\ni=1\n)'
it will give the result you want. A typical use would be
foo.get()
{
.sh.value="${foo.x}+i*${foo.y}"
}
to output a complex variable implemented as a compound variable.

Since the assignment is equivalent to c.hello=1, there is no assignment to
c, it currently prints nothing. I will look into changing this in
a future release.
