Is "access pattern" error?

[ababup1192]

In pony access pattern page:

https://patterns.ponylang.org/async/access.html

The following source code is

use collections = "collections"

actor SharedRegisters
  let _data: collections.Map[String, I64] = _data.create()

  be write(name: String, value: I64) =>
    """
    Write to the named register, setting its value to the given value.
    """
    _data(name) = value

  be read(name: String, fn: {(I64)} val) =>
    """
    Read the value of the named register and pass it to the given function.
    A register which has never been written to will have a value of zero.
    """
    fn(try _data(name) else 0 end)

This causes the following error

main.pony:17:22: call is not partial but the method is - a question mark is required after this call
    fn(try _data(name) else 0 end)
                     ^
    Info:
    packages/collections/map.pony:46:36: method is here
      fun apply(key: box->K!): this->V ? =>

Maybe I think a partial function.

 be read(name: String, fn: {(I64)} val) =>
    """
    Read the value of the named register and pass it to the given function.
    A register which has never been written to will have a value of zero.
    """
    fn(try _data(name)? else 0 end)

@ababup1192 - Yeah, you're absolutely right about what is needed - good catch!

I thought I caught everything that needed the partial call markers in #23 when I went through and updated everything, but I must have missed this snippet...

Do you want to file a PR to fix it? If you don't have time, I can come back and fix this a bit later.

This is fixed.
