Cannot parse empty constructor expressions

[jfecher]

Constructor expressions like MyStruct { field1: 3, field2: 5, ... } currently must be non-empty to avoid parsing conflicts when parsing an expression followed by an empty block. For example, in both if a {} and for i in 0..a {} we would otherwise end up being over-eager when parsing the expression, resulting in us parsing Constructor(name: a, fields: []) as the expression rather than just a.

It may need to be the case that if we parse an empty constructor expression we also need to check the token after it to make sure it continues the expression or is a terminator that is not{ (such as =, ;, or keywords like let, fn in the case of error recovery of a missing semicolon).

Still open, I haven't worked on it.
