In a very simple module test where I have the following functionSince I have explicit type annotations, I expect to get [3,5,7] when I load the module test and call func in ghci. However, I got
Consider these two programs and their attempted compilations.gcc 6.3, for example, gives error messages centered around Typo being an incomplete type, including
This question already has an answer here:It's better to express this behavior in the code:forEach(...) accepts Consumer, but why does the first example compile if List interface has following signature boolean add(E e)? whereas the second yields:
