I’ve been working on a macro which uses
$ in a special way. But for certain tests, I need to use
eval. Here is a very stupid MWE showin the problem, roughly
julia> macro with_dollar(x) if x isa Expr && x.head == :$ esc(:(y = 100)) else esc(:(y = 200)) end end; julia> @with_dollar $a 100 julia> @eval (@with_dollar $a) ERROR: UndefVarError: a not defined
Is there a way to tell
@eval to ignore it’s own rules about
$? How do other packages handle this?
