Cannot set a default value when using InputOption::VALUE_NONE mode

[glensc]

$ php71 test.php
Fatal error: Uncaught Symfony\Component\Console\Exception\LogicException: Cannot set a default value when using InputOption::VALUE_NONE mode. in vendor/symfony/console/Input/InputOption.php:159

seems to be issue with symfony 4.2:

$ composer show
mnapoli/silly             1.7.1   Silly CLI micro-framework based on Symfony Console
php-di/invoker            2.0.0   Generic and extensible callable invoker
psr/container             1.0.0   Common Container Interface (PHP FIG PSR-11)
symfony/console           v4.2.2  Symfony Console Component
symfony/contracts         v1.0.2  A set of abstractions extracted out of the Symfony components
symfony/polyfill-mbstring v1.10.0 Symfony polyfill for the Mbstring extension

Reproducer: https://gist.github.com/glensc/b28386f361db58f3c436e7b79460983b

tag v1 shows the problem:

git clone -b v1 https://gist.github.com/glensc/b28386f361db58f3c436e7b79460983b silly-51

@mnapoli am i using something wrong, or just not compatible with symfony 4.2?

[glensc]

downgraded symfony/console:

• v4.1.10 same
• v4.0.15 same
• v3.4.21 same
• v3.3.18 same
• v3.2.14 same
• v3.1.10 same
• v3.0.9 same

i'm not able to downgrade further with mnapoli/silly=1.7.1

[glensc]

had to downgrade to 1.5 for error to go away:

i'm able to avoid the error by renaming the option:

removing default value for $noLock = false also helper:
