Hello,
How would i use bquote to create names for a list.
e.g. to create list(a=10)
bquote(list(.(X)=10), list(X=a))

The best i could come up with is
bquote({ a=list(10);names(a)=.(X); a}, list(X=a))
which is quite ugly.
Is there an elegant way to solve this?

Q1: why is B different from A? In B, is a-a+1 getting evaluated

eval(quote(a-a+1),new.env())
a # 0
#B
a=0
eval(a-a+1,new.env())
