Ouch! I knew => was a comma in hash definition from the Llama but I didn't make the connection, sorry. But why would an author be using this form

? Is it just easier to read than it would be using a simple comma? Or does the special property of interpreting the word to the left of => as a string have a beneficial effect? Thank you for your kind help.
