What would you remove from Elixir?

[hauleth]

@Qqwy

• there is no sensible default value to give to the module

In general you should pass runtime configuration there.

@Qqwy

• the starting value is always the same, in which case it should not be specified in the caller

Why not? Also if we take into account above you will often change that value in tests.

@Qqwy

• The module has to set up its state after it was started (for instance because state setup takes too long or might fail), which means it will not have a state that is used yet until after init returns.

For this you have handle_continue/2 callbacks as you shouldn’t do long initialisations in init/1 either.
