I have a variable in a class with heredoc and it doesn't seem to be honored:
protected $usage = <<<'EOL'
db:table [<table_name>] [options]
Examples:
db:table --show
db:table --metadata
db:table my_table --metadata
db:table my_table
db:table my_table --limit-rows 5 --limit-field-value 10 --desc
EOL;
The first line and the last line are indented 8 spaces. Other lines are indented farther. I get an incorrect heredoc indentation error

I have my setting to use PHP 8.1 syntax. Supposedly this was finally allowed in PHP 7.3.
