Why? It currently returns a perfect make object!. Not to question your
knowledge, but to enlargen mine. ;)

Yes, & no:
nw-lyt: compose/deep[
wrd: [(first l)]
tp: [(second l)]
spc: [(third l)]
(if [length? l > 3] [
vls: fourth l
])
]
returns:
** Script Error: Out of range or past end
** Where: do-boot
** Near: fourth l
I guess compose doesn't execute an 'if?

because. ;) Well, it is difficult for me to explain... One reason is that
I need to be able to handle ALL parameters of a layout. If you look at the
object 'lyt which I have defined,
make object! [
wrd -- (word) The name of the layout
tp -- (type) Maybe I should use a different name, but it contains
'layout + any refinements
spc -- (spec) The specs of the layout
pr -- (parameters of the refinements) Currently it is not always
created, but I will probably change that
]
then the other reason is that the layouts get DOne when they are viewed. I
need them to not be in the global namespace. Block! maybe better, I am just
not sure.
Thanks!!
