[Issue 24634] Parse error initializing array from expression with StructInitializer

--- Comment #6 from Nick Treleaven <nick at geany.org> ---
basile-z is right that the compiler can't parse a struct initializer as part of
an expression. The ArrayLiteral spec was wrong - the pull fixes that.

Tom Kral:
> I find it rather surprising that StructInitializer would not work in this case. Is there a good reason for that?

It is part of a function argument, which in turn is part of an expression
initializer (because a function call is an expression). An expression cannot
parse all initializers because some initializers (e.g. `{}` for struct) mean
something else as an expression (a function literal). So initializers are not
accepted inside an expression.
