Implemented. IIUC for regexes it should be matched in a caller - or to make also an iterator for regexes?
```
  for (const auto &entry : m_map.equal_range(name))
    if (callback(entry.value))
```
```
  for (const auto &entry : m_map)
    if (regex.Execute(entry.cstring.GetCString())) {
      if (callback(entry.value))
```
