**Is your feature request related to a problem? Please describe.** I can't tell from the README how spotify and youtube(-dl) are used in savify, i.e. without digging through the code....

Merger on structs not supported

Running the following in the repl: `|| let b = merger[{i64, i32}, +]; merge(b, {1L, 2})` returns: `REPL: Compile error: Unsupported identity for binary op: + on {i64,i32}`

The intent is to reverse a string, i.e. a `vec[i8]`, however iter with negative step seems to be broken (at least on the master branch). Take the following examples: np.array([1,...

There's a [comment](https://github.com/weld-project/weld/blob/bd978e95206ec0e300480d035b9ed2155c3d5ac1/weld/codegen/llvm/llvm.rs#L3241) in the source saying pow is only supported for 'floats'. I presume support for integers would also be possible? EDIT: The following is actually incorrect Weld code....

Cast and literal

This produces wrong result on evaluation: |_inp0: vec[i64]| map( _inp0, |a: i64| a < 3L ) {'_inp0': array([0, 1, 2, 3, 4])} [] => [True False False False False] However...

Bitwise operation unexpected output

Evaluating this, where the inputs are np.arrays of dtype np.bool and return type WeldBIt: result( for(zip(_inp0, _inp1), appender, |b, i, n| merge(b, n.$0 & n.$1) ) ) {'_inp1': array([ True,...

I need to implement unique on an array of values _but_ preserving order. So for `[3, 3, 2, 4]` the result must be `[3, 2, 4]` not `[2, 4, 3]`...

As hinted by grizzly's groupby TODO, using `zip(group_on, zip(col1, col2))` would be nice, however that is not supported, i.e. the following is returned: `Unsupported expression: zip(col1, col2)` This forces one...

As raised in https://github.com/radujica/tospotify/issues/27, looks like some music players can store playlists with missing duration in `#EXTINF`, e.g. `#EXTINF:,Song` which leads to an exception such as ``` File "/home/serenity/.local/lib/python3.10/site-packages/m3u8/init.py", line...
