Feature suggestion. Implement is_XXX functions in the scripting language too

[bogzbonny]

I found it a bit confusing to have access to 'is_string()', 'is_int()' etc. in rust but not in rhaiscript... seems a bit cumbersome to have to type a.type_of() = "()" as opposed to just something like a.is_unit() in a script.

I tossed this in my rhai instance:

    #[rhai_fn(pure)]
    pub fn is_unit(inp: &mut Dynamic) -> bool {
        inp.is_unit()
    }

    #[rhai_fn(pure)]
    pub fn is_int(inp: &mut Dynamic) -> bool {
        inp.is_int()
    }

    #[rhai_fn(pure)]
    pub fn is_float(inp: &mut Dynamic) -> bool {
        inp.is_float()
    }

    #[rhai_fn(pure)]
    pub fn is_bool(inp: &mut Dynamic) -> bool {
        inp.is_bool()
    }

    #[rhai_fn(name = "is_string", name = "is_str", pure)]
    pub fn is_string(inp: &mut Dynamic) -> bool {
        inp.is_string()
    }

    #[rhai_fn(pure)]
    pub fn is_char(inp: &mut Dynamic) -> bool {
        inp.is_char()
    }

    #[rhai_fn(pure)]
    pub fn is_array(inp: &mut Dynamic) -> bool {
        inp.is_array()
    }

I considered this in the beginning but decided against it for the reason that it would introduce a new method of achieving something that can be done in another way.and the is_xxx API would need to be specific to known types.

I'm willing to put them in if enough people lobby for it though... As you know, it only involves defining those simple functions.
