Why are you using a dictionary ? Why not simply write

for [var, var2] in filter(items(g:), 'v:val[0]=~#"\\v^my_prefix"')
echo var."\t" var2
unlet var2
endfor

Is it because you want to avoid unlet ? But with the dictionary
I get some error message that it can't be displayed because the
nesting is too deep.
