<commit_before>^title Method Calls

Wren is deeply object oriented, so most code consists of invoking methods on
objects, usually something like this:

    :::wren
    System.print("Heyoo!") //> Heyoo!

You have a *receiver* expression (here `System`) followed by a `.`, then a name
(`print`) and an argument list in parentheses (`("Heyoo!")`). Multiple arguments
are separated by commas:

    :::wren
    list.insert("item", 3)<commit_msg>Fix small typo in method call documentation<commit_after>^title Method Calls
