re: One symptom of their failing: we can create lexically scoped generic
function definitions, but we can't create lexically-scoped class
Of course, this is not limited to CLASS definitions; a common thread of
complaint form the Lucid user community is the inability to make
lexically-scoped (and hence stack-allocated) defstruct definitions.
You mean defstruct instances, not defstruct definitions.
And in a sense, the continual call for "stack-allocated" LISTs and
ARRAYs begs for additional functionality in the language to express
Which X3J13 added not long ago in the form of the DYNAMIC-EXTENT declaration.
