[HELP NEEDED] understanding of function variable

[philippe-levan]

Is your feature request related to a problem? Please describe.

Hi,

When I look at the code, it seems that we can add a "function variable" into a template like $my_var(foo.bar)

Then in my json, I can add the variable "variables":{"my_var(foo.bar)":{"type":"text","value":"my_value"}}

and then all the string $my_var(foo.bar) is replaced by my_value.

Is there another feature associated to these "function variables" or it is just the way to have variables with a more flexible variable name (which is useful for me) ?
