Two issues:
First, it's
%options ghci
and not
%option ghci
Second, the \eval is executed in the context of the current file,
i.e., the source must be a valid literate Haskell file. An empty
literate file causes the literate preprocessor to fail. This
works for me:
--------------------------------
%include polycode.fmt
One
%options ghci
Two
\eval{4}
Three
> x = 0
--------------------------------
