+Reduce script parsing restrictions added by Babel.
+This was causing Babel to error when parsing partion scripts.
+
+```marko
+static const x = 1;
+export { x };
+```
+
+Before this change in the above code Babel would error when parsing `export { x }` saying `x` was not previously defined. This is because Marko parses these statements in isolation.
