We have an error message where we're missing the word "flag" or "option".

- This import is never used as a value and must use 'import type' because the 'importsNotUsedAsValues' is set to 'error'.
+ This import is never used as a value and must use 'import type' because the 'importsNotUsedAsValues' flag is set to 'error'.

This came up for fixes to svg-gradient() (less/less.js#3261). There are no automated visual regression tests, so it might be good to do so for functions that create visual assets. See: https://github.com/garris/BackstopJS

### Example
let unreachableProxy = "http://127.0.0.1:8888"
try:
  let client = newHttpClient(proxy=newProxy(unreachableProxy), timeout=1)
  var res = client.getContent("https://github.com")
  echo res
except:
  echo "Timed out"

Current Output

timeout variable is ignored, program stuck until default socket timeout will happen

Expected Output

Timed out a

Hmm, didn't we also had a sh256 hash next to this? That is way more useful for anyone downloading a static compiler from here and trying to verify it on CI (as that works with shasum -a 256 ).

After doing this the example in solc-bin docs should be updated to include such a hash too.

This is a follow-up to #4097 where we used an AtomicInteger as a poor-mans replacement for a Semaphore with tryAcquire (or maybe even drainPermits).

Should suppress --strict warnings.
