With strictmode set to 2.0 calling a function with myfunct(2,4) instead of the correct myfunct 2 4 will throw an error "The function or command was called like a method. Parameters should be separated by spaces"


Turn strict mode on and set it to version 1.0:

PS C:\> set-strictmode -version 1.0

C:\PS> $a -gt 5
The variable $a cannot be retrieved because it has not been set yet.
At line:1 char:3

Turn off strictmode (this is the default):

PS C:\> set-strictmode -off
