-------------------------------------+-------------------------------------
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.
{{{#!sh
#!/bin/sh
H='''
main = putStrLn "Hello, World!
'''
P='''
print("Hello, World!")
'''
R='''
puts "Hello, World!"
'''
stack ghc -- --version
bash --version
zsh --version
cat --version
python --version
ruby --version
echo '-----------------------'
cat <(echo -n "$H")
echo '-----------------------'
stack ghc <(echo -n "$H")
echo '-----------------------'
python <(echo -n "$P")
ruby <(echo -n "$R")
}}}
