Can't pass literal `$` as command argument

good : IO ()                                                                           
good =                                                                                    
  comp                                                                                      
    let dollar = "\$"                                                                      
    cmd.run `echo dollar sign: $dollar`                                                

main : IO ()                                                                                 
main = good

bad gives a syntax error:

test.ipso:4:33: error: expected one of: '"', '$', '${', '`', command fragment, space
  |
4 |     cmd.run `echo dollar sign: \$`
  |                                 ^

good is how I'm working around this.
