With process substitiution, ghc didn't read filedescriptor.
I ran ghc with process substitution as filename but ghc couldn't read the filedescriptor. I ran this script with bash and zsh, then I got the error.
#!/bin/sh
H='''
main = putStrLn "Hello, World!
'''
P='''
print("Hello, World!")
'''
R='''
puts "Hello, World!"
'''
