Puns for named application (#2890) Since it is common to want to assign a named argument a variable of the same name, we add special syntax for it. E.g. ``` f (fieldA : A) (fieldB : B) : S := mkS@{ fieldC := fieldA; -- normal named argument fieldA; -- pun fieldB -- pun }; ``` 2024-07-16 13:23:22 +03:00			`module Puns;`

Allow `@` in constructor declarations (#3099) * Closes #3041 * The old syntax without `@` is still accepted, but the formatter changes it to the new syntax 2024-10-15 20:15:37 +03:00			`mkS@{`

Allow trailing semicolons everywhere (#3123) * Closes #3039 * Closes #3043 * Closes #2970 * Closes #3089 * Parser allows trailing semicolons for any kind of semicolon-separated items: - let-block statements, - module statements, - record declaration statements, - record update fields, - record pattern fields, - named application arguments, - list literal items, - list pattern items, - open statement using/hiding items, - `syntax iterator` declaration parameters, - `syntax fixity` declaration parameters. * Formatter prints trailing semicolons if the items are displayed on separate lines, removes them if on a single line. * The formatting of multiline lists is changed to make it consistent with other semicolon-separated blocks: ``` [ 1; 2; 3; ] ``` instead of ``` [ 1 ; 2 ; 3 ] ``` 2024-10-29 20:25:06 +03:00			`fieldE : B;`
