E0002Syntax error

Reported by the compiler as an error or warning.

mettle explain E0002

The source tokenized correctly but does not follow Mettle's grammar.

Common cases and their fixes: if/while/match conditions require parentheses:
```
if (x > 0) { ... }        not    if x > 0 { ... }
```
every statement ends with ';'
a '{' must have a matching '}'
type annotations use ':', assignment uses '=':
```
var x: int64 = 1;
```

After a syntax error the parser resynchronizes at the next statement boundary and keeps going, so one mistake reports once, not as a cascade.
