macro expansion inside a block

macro expansion inside a block

[Andrea De Michele]

Hi all,
I want to expand a macro inside a block when the block is written and not when it is used.
Here a simple example:

\defineblock[myblock]
\hideblocks[myblock]

\starttext

\define\mynumber{1}
Some text: mynumber is :\mynumber 
\beginmyblock
  This is mynumber inside the first myblock, I want 1 and I obtain:  \mynumber
\endmyblock

\define\mynumber{2}
Some text: mynumber now is :\mynumber 
\beginmyblock
  This is mynumber inside the second myblock, I want 2 and I obtain:  \mynumber
\endmyblock

\useblocks[myblock]
\stoptext

This produce:

Some text: mynumber is :1
Some text: mynumber now is :2
This is mynumber inside the first myblock, I want 1 and I obtain: 2
This is mynumber inside the second myblock, I want 2 and I obtain: 2

instead I want:

Some text: mynumber is :1
Some text: mynumber now is :2
This is mynumber inside the first myblock, I want 1 and I obtain: 1
This is mynumber inside the second myblock, I want 2 and I obtain: 2

It is possible in some way?

no (at least not in a trivial way)
