Test

# Nimscript file
var i = 0

proc testInc =
  try:      doAssert false
  except:   return
  finally:  inc(i)

testInc()
doAssert i == 1

Result

stack trace: (most recent call last)
Test.nims(9, 11)
[...]/Nim/lib/system/assertions.nim(27, 20) failedAssertImpl

Same behavior with a try inside a block and break inside except.
