Patch 8.2.0563
Problem: Vim9: cannot split a function line.
Solution: Continue in next line so long as the function isn't done.

--- 210,222 ----
Note that "enddef" cannot be used at the start of a continuation line, it ends
the current function.
+ It is also possible to split a function header over multiple lines, in between
+ arguments: >
+ def MyFunc(
+ text: string,
+ separator = '-'
+ ): string
+
No curly braces expansion ~
