+Runs the following string a as a Lua statement. This is similar to an [expression](#expressions),
+but instead of the code evaluating to a value it must run a series of statements. Basically it allows
+for function bodies to be embedded into custom keybinds. All the same modules are available.
+If multiple strings are sent to the script-message then they will be concatenated together with newlines.
