Embed langage print when sourcing vim9script

[Ni Va]

Hi,

Is it normal to get print of embed langage when I source vim9script ?

Thank you

def g:SwitchFtHelper(): void # Syntax / Filetype - Helper {{{

  if ( !exists('g:cachebufnr') )
    g:cachebufnr = bufnr('%')
    g:cacheft = &ft
    StampedEcho( 'Cached filetype is ' .. g:cacheft .. ' and bufnr is ' .. g:cachebufnr )
  endif

  lua << EOF

print('foo')

EOF

enddef

When I source this I see nothing. Only when calling g:SwitchFtHelper()
(commenting out what doesn't work) I see "foo" printed. Looks fine to
me.

Thank you Bram!

Maybe it's because I forgot to say I have an autocommand. 

I am surprised to see out of print('LuaXmlParser') when I source this vim9script.

Thank you again Bram.
