Hallo liebe Leute. Hola gente. I'm starting with Haskell and i have some problems:

intercalate :: [t] -> [t] -> [t]

intercalate [a,b] [c,d] = [a,c,b,d]
intercalate (_) (_) = error "JOJO u cant do this"

Are there any form to restrict the parmaters that only allow to call the function intercalate with two arrays of two elements, in compilation time? Cause i cant write intercalete :: [t,t] -> [t,t]->[t,t,t,t].

Sorry for my bad english. I'm Argentinean.

Thanks!
