 # Analyzer's implementation of fromEnvironment assumes that undefined
 # environment variables have an unspecified value (rather than being
 # null) because it is expected that the user will supply a value when
 # the code is run.  This means that it produces slightly different
 # error messages than the VM and Dart2js.
