1) Vlang allows for struct a literal to be passed to the function, instead of named parameters.
2) Using this style, fields need not appear in the same order as they are declared
3) If one or more are omitted, their default values will be used instead.
4) The named parameter feature was deliberately omitted, for greater code readability.
5) Depending on the situation, variadic and/or sum types can also be considered.
