Optional args for TikZ style

I have a defined a TikZ style "midcircle" that decorates a path with, say, a small circle in the middle (with the decorations.markings library, setting "pos=0.5"). E.g.
draw (0,0)edge[midcircle](1,0);
would draw a straight line with a circle in the middle. Now I would like to be able to change the position of the circle by defining another style, say "midcirclepos", such that e.g.
draw (0,0)edge[midcircle,midcirclepos=0.7](1,0);
would draw the circle at "pos=0.7" instead "pos=0.5". I think I've seen such constructions, but I can't find any more how to implement it.
By the way, I can't use the usual default arguments for TikZ styles, because my "midcircle" already takes other arguments that also have defaults.

just put a variable in the value that you want to change like pos=#1 in your tikz style definition, then put the value midcircle=0.5, or another value like in this example see how it is defined InLineArrow style,

@JLeonV.: This doesn't work for me: The thing is that I want to have pos=0.5 as the default value, but I also have 2 other arguments passed to "midcircle" one of which also has a default value. However TikZ cannot handle more than one default value. (See last sentence)

Sep 5 at 14:20
My first guess would be that thepos=0.7still works, because it is a/tikzkey and not a/pgf/decorationkey. Otherwise you could usetikzsetmidcirclepos/.forward to=/tikz/pos, but without an MWE who knows for certain.

Define a key midcirclepos that takes as argument a value and stores it in the macro midcirclepos. Initialize it with 0.5 and use midcirclepos to access the value.
tikzsetmidcirclepos/.store in=midcirclepos,midcirclepos=0.5
Here is an example that also shows that the change to midcirclepos is temporary.
documentclassarticle
usepackagetikz
usetikzlibrarydecorations.markings
tikzsetmidcirclepos/.store in=midcirclepos,midcirclepos=0.5
begindocument
begintikzpicture[
midcircle/.style =
postaction=decorate,
decoration =
markings,
mark = at position midcirclepos
with draw (0,0) circle (0.1);
,
]
draw (0,0) edge [midcircle] (1,0);
draw (0,-1) edge [midcircle,midcirclepos=0.7] (1,-1);
draw (0,-2) edge [midcircle] (1,-2);
endtikzpicture
enddocument

@marmot What's wrong with macros in the context of a macro machine like TeX? Accessing a macro seems to be lightweight compared topgfkeysvalueof.
