No line number in error if a hashmap index has a type error

[jrfondren]

Code example

require 'hashmap'
require 'string'

local map: hashmap(integer, record{word: string, reading: string})
local row: record{id: string, word: string, reading: string}

local id = tonumber(row.id)
map[row] = { -- oops! should be: map[id]
  word    = row.word,
  reading = row.reading,
}

With output:

hasherrormsg.nelua:1:1: from: AST node Block
require 'hashmap'
^~~~~~~~~~~~~~~~~
error: in call of function 'hashmap(int64, V).__atindex' at argument 1: no viable type conversion from 'record{id: string, word: string, reading: string}' to 'int64'

Expected behavior

An error message pointing to the map[row], similar to

require 'hashmap'
require 'string'

local map: hashmap(integer, record{word: string, reading: string})
local row: record{id: string, word: string, reading: string}
local function set(k: #[map.type.K]#, v: #[map.type.V]#) map[k] = v end

local id = tonumber(row.id)
set(row, { -- oops! should be: map[id]
  word    = row.word,
  reading = row.reading,
})

Which has this output:

hasherrormsg2.nelua:1:1: from: AST node Block
require 'hashmap'
^~~~~~~~~~~~~~~~~
hasherrormsg2.nelua:9:4: error: in call of function 'set' at argument 1: no viable type conversion from 'record{id: string, word: string, reading: string}' to 'int64'
set(row, { -- oops! should be: map[id]
   ^~~~~~~
