Hi,
I’m following the Plutus Pioneer youtube videos currently in week3, and the sample code given usually has some of the type definition for example “GiveParams” which has the !PubKeyHash in it.
What is the exclamation mark “!” before the type PubKeyHash mean?
Also under the type VestingSchema has some definition “./” is that a Haskell syntax?
Apologies if this is explained further in the lecture, if so feel free to let me know, and I will be patient while I get to that lecture
Thanks
