array.index_of: string argument got mistaken as function?

[juchiast]

let array = ["hello"];
array.index_of("hello");

EXCEPTION: Function not found: hello (&str | ImmutableString | String, i64)
in call to function 'index_of' (line 2, position 7)

I believe index_of takes a closure that matches items.

If you put in a string, it looks up a script function of the same name.

Thats why it is looking for a function called hello.

There is an index_of that compares the passed value, only works with number

let array = [4, 5, 6, 19];
array.index_of(19);`

rhai/src/packages/array_basic.rs

Lines 823 to 833 in 169af8e

	pub fn index_of(
	ctx: NativeCallContext,
	array: &mut Array,
	value: Dynamic,
	) -> RhaiResultOf<INT> {
	if array.is_empty() {
	return Ok(-1);
	}
	index_of_starting_from(ctx, array, value, 0)
	}

It works for all types except string, where it got mistaken as name of a function...

The versions with function names as strings are deprecated but not yet removed for fear of breaking scripts.

Therefore unfortunately the depreciated version override the standard generic version.
