+To convert a string to a number use the C<:16($number)> notation where 16 is
+the base:
+
+    say :16("FF")           # 255
+    say :23("FF")           # 360
+
+Converting to a dynamic base requires the Rakudo internal function
+C<UNBASE()>:
+
+    my $base = 23;
+    say UNBASE($base, "FF") # 360
