[Haskell-cafe] Compilation of large data

Dear Café,

How can I compile large data in the source code? The data structure contains a few 
numerical and String constants and a long list of structures (containing two short lists of 

If I use ghci, it's fine, no problem (until some size). When I want to compile then I run 
out of memory (32GB, plus 32GB swap) on arch linux. Yes, machine with 256GB solved 
temporarily the problem, but only temporarily.

The data is generated (about 10.000 elements for the list and more). Should it be read 
from the file during the runtime? Should the structure be somehow decoupled (to small 
lists, each of them in a separate file)? Or there is no way, how to make it work... :-(

If I use different input, a bit smaller, which I can compile, the resulting binary is rather 
small, less than 7MB.
