Comment (by vanto):

 Replying to [[span(style=color: #FF0000, goldfire )]]\\
 OK. It is preferable to indicate the line where there is the syntax error.
 And the compiler does so in the majority of cases.
 Here what is the best solution?\\
 If the error is on the line {{{main}}}, do you move {{{main}}} to the
 right of two spaces? And so you create disorder in your code, or you
 correct the line above? If you correct the line above, GHC should indicate
 this line for correction. But perhaps this is too difficult to code?\\
 In this specific case what do you suggest?
