Tested the following...
 
\starttext
 
\useURL [myURL] [http://www.a.com] [] [wxyz]
 
1. \url[myURL] \blank
2. \goto{wherever}[url(myURL)] \blank
3. \goto{wherever}[{url(myURL)}] \blank
 
4. \goto{wherever}[url[myURL]] \blank
5. \goto{wherever}[{url[myURL]}]
 
\stoptext
 
It compiles, only 1. works though but it outputs a http://www.a.com hyperlink
instead of a wxyz hyperlink.
 
Output in attachement.

\starttext

\useURL [url] [http://www.a.com] [] [wxyz]   % this does NOT compile
