python2 -m virtualenv and python3 -m venv are two separate things. virtualenv is a pypi package and not included with python. virtualenv can be used with python3 instead of venv if desired (as nedbat does)

object properties are either data descriptors or accessor descriptors
data descriptors have a value property (and writable property)
accessor descriptors have get/set properties
I don't know why mdn for Object.defineProperty() refers to these properties as either optional or requied since all properties have default values
the default values are assigned during property definition if not present in the descriptors prototype chain
okay, even the default values on mdn for Object.defineProperty() are a lie (check case where object property already exists)
writable can be changed to false when configurable is false (interesting possible race?)
also, value attribute can be changed with Object.defineProperty() when configurable is false if writable is true
hm, assignment silently fails when writable is false but Object.defineProperty() TypeErrors (compatibility?)

> typeof foo
"undefined"

but

> foo
ReferenceError: Can't find variable: foo

if something has a type it should exist (imo)

the number of links to a directory is the 1 + number of subdirectories, because each subdirectory has a .. to the parent directory
