Adding inline comments to filters for readability

[9numbernine9]

Please describe your feature request.
Greetings! 👋

Would it be possible to add support for comments inside of filters, i.e. a way to document more complex filters? I'm writing a fairly complicated filter for use inside of a bash script and I would like to write some documentation inside of the filter for each step of the filter so that the future maintainer (i.e. probably me) will understand what's going on. 😅

Describe the solution you'd like

I'd like it to be possible to define a filter across multiple lines, and have lines that start with # be considered as comments and ignored until the end of the line.

In bash I'm imaging that it could be used something like this - first defining the filter:

filter=$(cat <<'EOF'
# Pretend that this is a comment for a very complex filter
.
EOF
)

And then could be invoked thusly:

yq "$filter" file.yaml

Currently, however, this just prints an error: Error: 1:1: invalid input text "# Comment here..."

Describe alternatives you've considered
N/A

Additional context
This is supported nicely in jq and it would be nice to have this feature here too!
