[Proposal] EEx: Allow a comment to follow `end`, e.g., <%= end # comment %>

[Richard Michael]

In complex EEx templates I find it helpful to document the end of control-flow or loop statements.  For example:

<% if cond do %>

...long content

<% end # cond %>

Unfortunately, this results in compiler syntax error with "unexpected token: end".

However, EEx does accept "to end of line" style comments with other statements.  For example:

<%= if cond, do: "foo" # a comment %>

<%= "foo" # a comment %>

As workaround I can use:

<% end %><%# if cond %>

Rather clunky, especially since end of line comments compile elsewhere.

Could the EEx compiler be enhanced to accept a comment following `end` ?

This seems not too complicated, I am happy to work on it with a bit of guidance.

(Apologies if I have simply made a mistake or overlooked EEx usage.)

Regards,

Richard

I would use it if such a feature were included.

I would use this as well! I opened an issue with repro steps: https://github.com/elixir-lang/elixir/issues/10256
