Compilation time increases too much with array's size

What is wrong?

The compiler takes too long (practically freezes) when compiling the following code:

contract Test {
    pub fn foo(bar: Array<u256, 10000>) {}
}

I'm running the Mac version, with:

$ fe --version
fe 0.20.0-alpha

$ fe build --output-dir mytest test.fe

It does work with relatively small array sizes. But the bigger the array size, the longer it takes. To the point it's unusable for large ones. Some numbers:

size	time
10	0.08 sec
100	0.48 sec
1000	30 sec
10000	killed after +30 min.

Interestingly enough, adding --emit yul speeds things up a lot.

Here's the output I got from compiling the same contract with the --emit yul flag: https://gist.github.com/tinchoabbate/8900ac384c46a87fb843113bab1d56e9

Seems like the generated Yul could use a for loop? Perhaps that's why it's taking too long when compiling to bytecode ?
