1 maybe 2 issues with 'AboutMeasureObject.Koans.ps1'

[ghost]

ISSUE 1: 'can operate on object properties'

Well Averages can be challenging especially when the resulting average can have a seemingly endless number of significant digits. I would propose that you limit the number of significant digits in some manner otherwise it is going to be hit and miss for passing this test.

Original Line 80:

__ | Should -Be $Data.Average

Modified Line 80:

__ | Should -Be Should -Be ([math]::Round($Data.Average,4))

ISSUE 2: 'can measure text lines, characters, and words of strings'

EXCEPT when the file does not exist, then the answers are always zero (0). If this was your intent then this isn't an issue, otherwise it might be wise to have a file that exists as part of the data. I just picked a file and plugged it in.

Original line 84:

$Text=Get-Content"$(Get-PSKoanLocation)/Foundations/AboutTheStockChallenge.Koans.ps1"

Modified line 84

Depends on the intent of the developers.

Yeah, agreed on the rounding issue. For the latter point, it might be a better call to simply include a few lines of text in the koan file itself rather than trying to read another file.

How about this for a modification to line 84

$Text = Get-Content $PSCommandPath

This may have some folk scratching their heads, until they google it, of course.
