 Performs a semantic pass across a project from the entry point `file`. A first pass traverses the top-level scope after which secondary passes handle delayed scopes (e.g. functions). These secondary passes can be, optionally, very light and only seek to resovle references (e.g. link symbols to bindings). This can be done by supplying a list of expressions on which the full secondary pass should be made (`modified_expr`), all others will receive the light-touch version.
