+Integers and floats can have their numbers separated with ``_`` to make them more readable.
+The following ways to write numbers are all valid::
+
+    12_345_678  # Equal to 12345678.
+    3.141_592_7  # Equal to 3.1415927.
+    0x8080_0000_ffff  # Equal to 0x80800000ffff.
+    0b11_00_11_00  # Equal to 0b11001100.
