Pattern match a struct using %_{}, How does that work?

I have seen the pattern %_{} being used to match against structs (notice the _ after the %).
Is this documented somewhere? It seems to match structs but I’d like to know if I am misisng something.

I’m not sure if there is real documentation around this. But at least, I found in the 1.3.0 changelog this:

  • [Kernel] Allow variable struct names when matching, for example, %module{key: "value"} = struct

For me this implies more or less, that I can also use _ as a name to bind to.


Wow, that makes sense, I thought it was special syntax :smiley:
