Need help understanding strings and concatenation

[glossy nova]

.{} not {}

also that won't be a valid format string, so actually std.debug.print("{s}", .{alphabet2});

[obsidian terrace]

.{} creates an anonymous structure

It's usually used to coerce to real structure or array, but in the case of the print/format functions, the parameter is anytype

Because it iterates recursively through the fields to print them
