Hi Tom,

Thanks for your detailed instructions about splitting YHI into two parts and then loading bytecode from the heap. I followed them, and was able to generate a file to be loaded into yhi.
However, upon compiling I get some nasty errors that I'm unable to figure out. Below is a snippet from a factorial function:

fac 0 = 1
fac n = n * fac (n-1)

main = print (fac 42)

When I compile I get these errors for this section of code

------------------------------------------------------------

Any ideas about why that blows up? In particular I'm curious about this error, "error: initializer element is not constant" not sure what it means.

Thanks for the help,
