A #record's *canonical* constructor has one arg per component but in its *compact* form, you don't have to list them. You also don't have to (in fact, can't) assign fields, just do the checks/reassignments you need, rest happens automatically.

Serialization works great with #records, no black magic needed! The guaranteed presence of constructor parameters and accessors makes serialization work with the object model and makes it easy to create reliable serializable records.

Since this article doesn't seem to have any interactive element to it, I'm going to hold a series of polls to determine the winner: #DemBracket #DemPrimary2020 #2020Polls #MarchMadness #BracketOfRandomThings #Bracketology #FITN @TheDemocrats
First matchup in the #Lefties portion of the bracket! Of these 2, which would you rather support in the 2020 Democratic primaries for president?
1. @SenSanders i.e. @BernieSanders #Sanders2020
2. @ninaturner #Turner2020

(Oops, I forgot to include the seeds; Bernie is 1st seed and Nina is 8th seed. The '1' and '2' by their names aren't seeds, but rather correspond to the poll options. I'll fix this in the rest of them, seeing as someone's already voted in this one.)
