Record Types |

|
Record Expression |
Syntax: {f1 = e1, ..., fn = en} where, as always, each ei can be any expression. Here each f can be any field name (though each must be different). A field name is basically any sequence of letters or numbers.
Type-check: Type-check each expression to get some type ti and then build the record type that has all the right fields with the right types. Alphabetized by REPL when printed.
Evaluation: Evaluate each expression to a value and create the corresponding record value. |
|
|
"By Name" access |
used for larger compound types |
|
|
"By position" access |
used for smaller compound types |
