There's no such built-in functionality in the language or 
standard library, no. As Jonathan pointed out, this has been 
implemented as a template multiple times, though. Here's my 
version:

https://gist.github.com/Biotronic/fffa7d4c96d760da5129d27ba3307f73

Usage:

named!executeShell("my_command", args.workDir = "my/path")

Missing functionality:
No support for overloads. Sorry.
No handy suggestions for which argument you may have meant when a 
typo sneaks in.
