In line or 'local' variable option when making matches?

[elminster3k]

When doing pattern captures, I'm wondering if there is a way to set the variable during the capture, maybe thought of as a local scope variable, for example, rather than this:
{My name is %1} {#var name %1}
It would be something like this:
{My name is {$name}} -- Just making up syntax here, since I'm not sure what this would look like..
So in the second example, the variable is defined as it makes the match, scoped locally for that action only etc.

It's not possible, if you want to assign variables in a substitution you could use something like this:

#sub {My name is %1} {My name is @setvar{name;%1}}

#function setvar {#var {%1} {%2};#return {%2}}
