Then to make iemlib/split.pd_darwin work as [split], one would use

Syntax suggestion: what about [declare -import iemlib]?
Some consensus on how to do things like that ("keyword arguments") ould
help:
1. In Flext/Jitter style: [declare @import iemlib].
2. In Unix/Tcl/Toxy style: [declare -import iemlib].
3. In GridFlow style: [declare, import iemlib], where "import" is a
selector and the name of a method, and the comma is like [initbang].
The use of "@" to mean "attribute" may remind of Ruby, but in Ruby, "@"
is a kind of variable, not a kind of argument.
The GridFlow style relies on the ability to replace keyword arguments of a
constructor by a bunch of little messages that modify the object just
after it's constructed (this is not always possible).
One of (1) and (2) is redundant. Then I wouldn't know which of that or (3)
to pick. The (3) has the important concept that every option is
runtime-configurable. That might not be an issue for [declare], but that
is an issue for other object classes that [declare] would be consistent
with.
How would you specify multiple imports? It may make the difference between
Unix style and Tcl style:
[declare -import foo -import bar] <- unix
[declare -import {foo bar}] <- tcl
because in tcl style, every time an option is specified, it has to
completely override the existing option of the same name: it can't add up
like pd's -lib -path -helppath. Pd doesn't accept {} so here are some
possible replacements:
[declare -import (foo bar)] <- GF-style nested lists
[declare -import foo bar] <- use dash-prefixed symbols as delimiters
[declare, import foo bar] <- use comma as delimiter
