My recommendation was to remove the alias this in DirEntry that
tried to turn it into a string. A DirEntry is not a wrapper for
a string, in particular, it does not support range primitives,
which is why the string functions failed when changed to have
InputRange parameters. Adding range primitives to DirEntry
would cause other weird problems, because DirEntry is
fundamentally not a range (a range 'consumes' its data via
popFront() which makes no sense for DirEntry).
Yes, that breaks:
DirEntry direntry;
remove(direntry);
which must be rewritten as:
DirEntry direntry;
remove(direntry.name);
and we're not supposed to break existing code. But the
alternative, which is redoing every template that accepts an
InputRange, seems an awfully heavy burden.
DirEntry is not the only source of problems. For example, the
rangification also broke ae.utils.funopt, which also uses structs
with an alias this'd string.
