This document contains a list of issues and annoyances that we have writing

Gleam code today, so that we can devise solutions to them in future.

There are other annoyances that have known solutions that are yet to be
7

implemented. These are tracked in the Gleam issue tracker instead.

24

bytecode compiled for it is not easy to distribute.

JavaScript runtimes do better, but it is still not as good an experience as
27
+
languages that compile to a single binary, and forcing Gleam programmers to use
28
+
promises and a single thread is not ideal.

## Runtime debugging is basic

## Last of if/else makes boolean logic less pretty and more alien
