Hi all,

I can’t explain the following behavior of the .tuc writer. When
passed a nested hash, context fails on the second pass if the
array part of the first nesting depth is empty:

·······································································

%% the commented lines work
\startluacode
  job.variables.tobesaved.foo = { bar = {  } }
  -- job.variables.tobesaved.foo = { "works now",  bar = {  } }
  -- job.variables.tobesaved.foo = { bar =  "works too" }
\stopluacode

\starttext foo \stoptext

·······································································

I get this error:

·······································································

Bug?
