Steve,
It's not exactly prose, but the error message is correct. It says:
"Error: new can only create structs, dynamic arrays or class objects,
not char[]'s."
So:
1. You didn't try to allocate space for a struct (e.g. new struct_t.)
2. You didn't try to allocate space for a dynamic array (new char[5].)
3. You didn't try to allocate space for a class object (new Class.)
From your code, it's obvious what you were meaning to do, so I would
agree that changing this would be good. Options I see are:
1. Improve the error message, e.g.: "Error: new can only create structs,
sized dynamic arrays, or class objects; char[] cannot be created."
2. Change the compiler to react as if you used new char[0].
3. Special case the error message, e.g.: "Error: new can only create
dynamic arrays with an initial length, use 0 for empty."
Best answer yet! You win a free holiday in Tanzania (as long as you pay to get
there). Yes it would be great if the error message gave you clue about
specifying the size. Then, all the magic is removed, and you know just where
you are. But even then, zero would be quite a good default!
I don't mean to ruin anyone's holiday in Tanzania but zero is a crappy
default. When I say new char[] it's not like I'm really hoping for a
shortcut for new char[0]. It's more likely new char[] is really
originating as new T where T = char[].
