Interesting. I didn't think to use dump to check differences.
Another followup question. After using dump on some simple if statements,
I've noticed that all blocks induce this LineNumberNode which is messing up
the equality.
Is there a way to ignore these nodes in the equality check? They show up in
any kind of block statement (function, if, etc)
eg:
dump(:(if true 1 else 0 end))
Expr
head: Symbol if
args: Array(Any,(3,))
1: Bool true
2: Expr
head: Symbol block
args: Array(Any,(2,))
1: LineNumberNode
file: Symbol none
line: Int64 1
2: Int64 1
typ: Any
3: Expr
head: Symbol block
args: Array(Any,(2,))
1: LineNumberNode
file: Symbol none
line: Int64 1
2: Int64 0
typ: Any
typ: Any
dump(Expr(:if, true, Expr(:block, 0), Expr(:block,1)))
Expr
head: Symbol if
args: Array(Any,(3,))
1: Bool true
2: Expr
head: Symbol block
args: Array(Any,(1,))
1: Int64 0
typ: Any
3: Expr
head: Symbol block
args: Array(Any,(1,))
1: Int64 1
typ: Any
typ: Any
They're the same minus LineNumberNodes, because block type expressions
always create those things.
