## DexLabel
- DexLabel(name)
+ DexLabel(name [, **on_line])
Args:
name (str): A unique name for this line.
+ Keyword args:
+ on_line (int): Specify a line number to label.
+
### Description
-Name the line this command is found on. Line names can be referenced by other
-commands expecting line number arguments.
+Name the line this command is found on or 'on_line' if it is provided. Line
+names can be referenced by other commands expecting line number arguments.
For example, `DexExpectWatchValues(..., on_line='my_line_name')`.
### Heuristic

+ except KeyError:
+ # We cannot use self.lineno because it hasn't been set yet.
+ pass
+ if kwargs:
+ raise TypeError(f'unexpected named args: {", ".join(kwargs)}')
