Jump to a function from where it is called

When writing/debugging code you often want to jump from where a subroutine/function is called to where it actually is . Hitting the "*" key is frustrating if the sub/func is called many times. The following mapping solves the problem. (Notice how it can be altered for other lanaguages)
nmap gx yiw/^\(sub\<Bar>function\)\s\+<C-R>"<CR>
Instructions: Place cursor over called function (normal mode) and type
 How it works
- Yank inner work to un-named register
- search for sub or function followed by 1 or more spaces
- Retrieve un-named register
- Start Search
Information also included in VimTip305.
What language is this supposed to work in? Basic??
- Probably perl, which also uses sub for functions
I suggest to modify mapping: nmap gx mryiw/^\(sub\<Bar>function\)\s\+<C-R>"<CR>
thus allowing reverse jump by typing `r
