+DTree DTree::get_by_path(String path, String delim = "/")
+
+:params
+path : slash-delimited path to traverse
+delim : optional path separator
+return value : the resolved child node, or an empty `DTree` when the path cannot be followed
+
+:desc
+Traverses a nested `DTree` without creating missing keys.
+
+Empty path segments are ignored, so leading and trailing `/` characters are harmless. If any intermediate node is not a map or a segment is missing, `get_by_path()` returns an empty `DTree`.
+
+Typical usage:
+`context.cfg.get_by_path("theme/options/portal-dark/label").to_string()`
