llist: Make a finite lazy object from R's object

In TobCap/lazystreamr: Provides basic functions that handle lazy stream objects

Description

functions to construct and coerce lazy stream

Usage

llist(...)

llist_lazy(...)

as.llist(x)

Arguments

...	non lazy-stream object,
x	any type of object

Examples

x <- llist(1, 2, 3) # arguments are evaluated
# y <- llist(1, repeat() {}, 3) # cannot return
z <- llist_lazy(1, repeat{}, 3) # can be defined
lhead(z) # => 1

# Convert R's vector (include R's list) to llist
# is.llist(as.llist(x)) is ALWAYS TRUE
as.llist(1:3) # => llist(1,2,3)

llist(1, list(2, 3))
# => llist(1, list(2,3))
# => only the first layer is converted
