No, lout doesn't provide ], it's how pdfmark is to be used.  [ and ]
are not syntactic in PostScript, they are just operators.  "[" is a
synonym for "mark" (and "<<").  "]" is an operator that uses stack
contents up to the nearest mark to create an array.  "pdfmark" uses
the stack contents up to the nearest mark to create a PDF object in
the produced PDF.  Lout emits in its standard prologue this
boilerplate code

  /pdfmark where {pop} {userdict /pdfmark /cleartomark load put} ifelse

that aliases "pdfmark" to "cleartomark" if pdfmark doesn't exist, so
that the whole [ /key value ... pdfmark segment would be ignored if we
the output is processed e.g. by a printer.
