Hi all,
Joe added a new word to the namespaces vocab:
: initialize ( name quot -- )
It encapsulates a common idiom where you want to set a global variable
in a top-level form but only if it hasn't been set before. People
would re-invent various ways of doing this all over the library:
foo global [
H{ } clone or
] change-at
foo global [
[ H{ } clone ] unless*
] change-at
foo global [
H{ } assoc-like
] change-at
foo get-global [
H{ } clone foo set-global
] unless
... and so on. Now you just write
foo [ H{ } clone ] initialize
