Hello Ron,

thank you, but it was not the run-time stack size I meant. It was the stack size for nested types which defaults to 20 or so IIRC. My nested types currently go to about 23 deep.

Hi,

I'm using deeply nested types in my app and exceed some stack-size in
ghci.

I can't remember the runtime option I have to pass to ghci anymore,
it's been about a year since I last pursued this approach.
ghci +RTS --help suggests -K<size> Sets the maximum stack size (default 8M)
Egs: -K32k -K512k. ghci is just another Haskell program which uses the
GHC RTS.

Is it also possible to set this stack-size via pragma in the source code?
Via an OPTIONS_GHC pragma, if possible.
