The Arrays spec, under the "Strings" section, has the following example code:

wchar w;
w = \r; // w is assigned the carriage return wchar character

This code does not compile: cannot implicitly convert expression ("\x0d") of
type char[1] to wchar. Trying to explicitly cast it to wchar[1], wchar[], or
wchar also fails with similar error messages.

Yet, the spec says right above this code that "[s]trings a single character in
length can also be exactly converted to a char, wchar or dchar constant".

Which is correct? To solve, change compiler behaviour to make the code compile
and then change the 'w = "b"[0]' part of the code to 'w = "b"', or remove the
sentence quoted and change the 'w = \r' line to 'w = \r[0]'.
