String interpolation not working in closure

I am looking at GString $ keyword and want to print the range. 

('A'..'Z').each {item ->
    print '$item'
}

I was expecting the range A..Z to be printed, but its printing $item$item.... What am I missing here?

Single quoted strings are java.lang.String and interpolation doesn't work here. You need to change it to GString, use double quotes:

('A'..'Z').each {item ->
    print "$item"
}

It's explained pretty well in Groovy's documentation about strings.
