Bug 15368 – Improve error message for "auto" keyword inside "foreach"

Users may attempt to do type inference in foreach statements in the following way: foreach (auto e; foo) { } However, this causes the following compilation error: >Error: basic type expected, not auto This can be fairly misleading as an inexperienced programmer may assume that type inference is not possible inside foreach statements, as the compiler says it expects a basic type (when it syntactically actually doesn't). As per http://forum.dlang.org/post/[email protected] I suggest adding a special case if the unexpected token inside a foreach statement's declaration is "auto", pointing out that "auto" is neither needed nor allowed in this context to get type inference.
