This subject was initially discussed in https://discourse.julialang.org/t/efficient-way-to-split-string-at-specific-index/83115/17 regarding a way to split a string into equal-length substrings.

The solutions discussed involved (for a string composed of 10 blocks of 8 strings)

• using a comprehension split8(str::String) = [str[i+1:8] for i in 0:8:length(str)]
• using a comprehension and `S

When doing division and modulo operation with constant or immutable denominator it is possible to only do compile-time denominator check and skip runtime checks.

Consider following contracts:

pragma solidity 0.8.15;

uint256 constant _MODULE = 17;

contract C1 {
    function f(uint256 a) external pure returns(uint256) {
        return a % _MODULE;
    }
}

contract C2

This code is a bit bogus. If opt can be NULL, the declaration typecheck_t* t = &opt->check; could crash the compiler. In any case, it looks like the t declaration could be safely moved into the scope of the if-branch, where it is properly guarded against opt == NULL.

Motivation

The Git class currently doesn't support submodules which prevents for example using submodules in Quark repos.

Description of Proposed Feature

Add a submodule method to Git and add submodule recursion to the Quark install step, eg adding the --recurse-submodules git flag to the clone command. This will download an

Throw away the manifest and re-resolve the deps.
