How to make variables declared inside static blocks available?

[Vindaar]

`static` opens its own scope, so outside of it the variable is not defined. You 
can instead use a `static` expression and assign it to a `const` variable like 
so (and in principle just directly call `toTable` instead of having `v2` and 
`v3` separately, unless you need `v2` itself somewhere):
    
    
    import std/[parseutils, strutils, tables]
    
    const v2 = static:
      let v1 = "data.csv".slurp.splitLines
      var res = newSeq[(string, uint)]()
      
      for pair in v1:
        let splitted = split(pair, ',')
        if len(splitted) > 1:
          res.add((splitted[0], splitted[1].parseUint))
      res
    
    const v3 = v2.toTable
    echo v3
    
    
    Run

(note that you could keep the name `v2` inside of the `static` block, but I 
changed it for clarity)
