Hi! Within the program I have coded, I arrived at a place where I have the following Expr: ex = :(Float64[32]) Is there any way to extract the number within brackets without doing ex_str = String(Symbol(ex)) num = match(r"\[\d*\]",ex_str) ? Thanks!

Regex on an Expr

julia> ex = :(Float64[32])
:(Float64[32])

julia> number = ex.args[2]
32
