//@ ### test(expression)
//@
//@ Available expression primaries:
//@
//@ + `'-b', 'path'`: true if path is a block device
//@ + `'-c', 'path'`: true if path is a character device
//@ + `'-d', 'path'`: true if path is a directory
//@ + `'-e', 'path'`: true if path exists
//@ + `'-f', 'path'`: true if path is a regular file
//@ + `'-L', 'path'`: true if path is a symbolic link
//@ + `'-p', 'path'`: true if path is a pipe (FIFO)
//@ + `'-S', 'path'`: true if path is a socket
//@
//@ Examples:
//@
//@ ```javascript
//@ if (test('-d', path)) { /* do something with dir */ };
//@ if (!test('-f', path)) continue; // skip if it's a regular file
//@ ```
//@
//@ Evaluates `expression` using the available primaries and returns corresponding value.
