weird syntax error, mentioning vlib/net/http/header.v:376 instead of the originating source file, doing `_ := http.Response{header: http.new_header{} }`

What did you do?
./v -g -o vdbg cmd/v && ./vdbg x.v && x

import net.http
_ := http.Response{header: http.new_header{} }

  

What did you see?

vlib/net/http/header.v:376:22: error: invalid expression: unexpected token `)`
  374 | // new_header_from_map creates a Header from key value pairs
  375 | pub fn new_header_from_map(kvs map[CommonHeader]string) Header {
  376 |     mut h := new_header()
      |                         ^
  377 |     h.add_map(kvs)
  378 |     return h

What did you expect to see?

a more sensible error, mentioning the source file, not the imported module (which is syntactically valid)
