Came across this while working on removing autodecoding.
If you have an enum that derives from char (this comes from std.algorithm.comparison):
enum EditOp : char
{
none = 'n',
substitute = 's',
insert = 'i',
remove = 'r'
}
Then isSomeChar!EditOp is true.
However, EditOp[].byDchar does not work, because decodeFront cannot handle EditOp. The reason is because the decodeImpl return structure is hard coded to only accept char, wchar, or dchar EXACTLY.
Instead it should accept any range that has a character element type, and check the size of the character to ensure it works (this is purely a template constraint problem, the code works fine once you fix it).
