	* In Python, if only one argument is given, it is considered ''stop'' and the resulting sequence counts from 0 up to (but not including) that value.

 Variables in both Python and MiniScript are local by default.  There are some subtle differences, however: in Python, an inner function can implicitly access the variables of an outer function, but ''can't'' implicitly access global variables, while in MiniScript, any function can implicitly read values from both the outer context and the global context.  To update a global variable, where Python uses a special <c>global</c> statement, MiniScript uses a <c>globals</c> prefix in a manner similar to using <c>self</c> to access object data.

		+
		+	While not part of the core language, several MiniScript environments (including [[Mini Micro]], [[Soda]], [[command-line MiniScript]], and [[Farmtronics]]) support an [[import]] command. However the semantics are a bit different from Python.
		+
		+	In MiniScript, the module name must be a string (usually, a string literal). The [[import]] command searches for a corresponding script file, runs it in its own call context, and binds the result (as a map) to an identifier of the same name in the calling context.
		+
		+	<ms>import "mathUtil"
		+	print mathUtil.dice(3,6) // rolls 3d6 and prints the result</ms>
		+
		+	Note that [[import]] always runs the code in the imported module, even if it was run before. See the Usage Notes under [[import]] for an <c>ensureImport</c> function that may be helpful to ensure a module is imported only once.
		+
		+	MiniScript does not support the ''from'' syntax (e.g. Python's <c>from math import pi</c> or <c>from math import *</c>).
