Error in Ruby code embedded in vim9script

Hi all,

I got an error using Ruby code embedded in vim9script, seems something has changed in vim9script in this case. Like it understand $ as begin  of a range no ?

Thank you

Error detected while compiling command line..function readxml#mainruby[1]..<SNR>131_rubyCaller:

line    8:

E1050: Colon required before a range: $LOAD_PATH << Vim::evaluate('expand("$vim/extensions/ruby/lib/ruby/3.0.0")')

This is the code

enddef

def s:rubyCaller()

ruby << EOF

$LOAD_PATH << Vim::evaluate('expand("$vim/extensions/ruby/lib/ruby/3.0.0")')
