First look

[neo]

First hours testing nim, I am encountering the following:
    
    
    import os, cpuinfo
    
    echo getCurrentCompilerExe()
    
    echo ("\nProcessor count ", countProcessors())
    
    stdout.writeLine "produces no output"
    
    Run
    
    
    : undeclared identifier: 'getCurrentCompilerExe'
    
    Warning: a [b] will be parsed as command syntax; spacing is deprecated
    
    
    Run

Is getCurrentCompilerExe only intended for the Windows platform but not 
documented?

Can the a [b] warning be improved upon?
