ParserError during PowerShell script execution - Bug or design?

Just now, Mike Moniz said:

groovy can import internal/collector functions like hostProps.get() without having the collector needing to directly modifying your code with search-replace

Yes, that is true. What I mean is that to escape a quote in a string in Groovy, you do it the same whether it's single quotes or double quotes encapsulating the string:

def string1 = "mystring\"withquotes"
def string2 = 'mystring\"withquotes'
assert string1 == string2
